There's probably not a single person who hasn't heard of The Big Bang Theory. The hit show, which first aired in late 2007, has been always been on television's top-10 most-watched series every year in seven out of its 12 seasons. The 12th and final season is going to end sometime in 2019. The show has been nominated for 216 Awards, winning 56 so far. As expected, it has brought tons of fame and huge earnings to its stars, who are now considered celebrities. Let's check out some of The Big Bang Theory's most acclaimed actors, as well as their real-life partners!

Simon Helberg & Jocelyn Towne

The Big Bang Theory is full of hilarious figures, and one of the funniest is definitely Howard Wolowitz, portrayed by Simon Helberg. Helbert has received a lot of praise for his portrayal of Wolowitz, while he's also won a Critics' Choice TV Award for Best Supporting Actor. Helberg has been married to actress Jocelyn Towne since 2007. Today, they have two children, Adeline, born in 2012 and Wilder, born in 2014.  They seem to be madly in love, and they've always wanted to turn their love story into a movie. Their film, We'll Never Have Paris, released in 2014, was based on the story behind their engagement.

Johnny Galecki & Alaina Meyer

Johnny Galecki skyrocketed to stardom as Leonard Hofstadter in The Big Bang Theory, but he has actually played in a ton of TV shows. Galecki is currently one of the highest-earning TV actors, with his salary being estimated around $900K per episode. He's also played in several episodes of Roseanne, while he's also appeared in popular films like National Lampoon's Christmas Vacation, I Know What You Did Last Summer and Rings. Reportedly, Galecki and his co-star Kaley Cuoco used to be in a relationship for a couple of years while they acted together, but they eventually split, and in 2018, he appeared at the Golden Globes with his new girlfriend, Alaina Meyer.

Kaley Cuoco & Karl Cook

There's not much to say about Kaley Cuoco, as we bet you already know this blonde beauty. Cuoco first became famous when she starred in 8 Simple Rules back in the mid -2000s, but it was her Big Bang Theory role that made her a household name in American television. Portraying Penny, Cuoco won several Awards and even her own Hollywood Star in 2014. In 2017, she also founded her own production company called Yes, Norman Productions. Cuoco started dating equestrian star Karl Cook in 2016, and their wedding two years later was a major celebrity event. Before that, she was married to tennis player Ryan Sweeting.

Jim Parsons & Todd Spiewak

Does Jim Parsons even need an introduction? His face has been everywhere on TV during the last couple of years, even if most people know him as Sheldon Cooper from The Big Bang Theory, a role which brought him from obscurity into absolute stardom. His Sheldon character earned him four Primetime Emmy Awards and a Golden Globe (we won't even mention his huge earnings). Parsons, who currently works as a narrator for the said TV show's spin-off, Young Sheldon, married Todd Spiewak, an art director, in 2017, while reports have claimed that they've been together for at least a decade.

John Ross Bowie & Jamie Denbo

John Ross Bowie became famous after playing Dr. Barry Kripke on The Big Bang Theory. Though he had landed other roles before that, this one has remained his breakthrough appearance. Bowie has also made a lot of money by appearing on Ford commercials, while he's an occasional author for Go Metric and The New York Press as well. Since 2016, Bowie has been starring in Speechless, while in 2018, he voice-acted on Big Hero 6: The Series. Back in 2004, he tied the knot with actress Jamie Denbo who used to play on Ghostbusters. Together, they have two children.

Mayim Bialik & Michael Stone

Mayim Bialik is our beloved nerdy neuroscientist Amy Farrah Fowler on The Big Bang Theory. This role granted her a Critics' Choice Award and many other nominations, but Bialik's TV activity started way back. In fact, Bialik starred in Blossom as the title character in the early '90s.  Amazingly, Bialik is a neuroscientist in real life as well, and she's also released her own books, with the most recent one titled Boying Up, released in May 2018. Bialik was married to Michael Stone from 2003 to 2012. They stay on good terms as, even if they're not together anymore, they have two children together.  

Wil Wheaton & Anne Wheaton

Well, you've certainly been familiar with Wil Wheaton long before he played in The Big Bang Theory. That wasn't one of his most famous roles after all. Wheaton gained attention after starring in Star Trek: The Next Generation, while he's also played in the iconic film, Flubber. He's done tons of voice-acting in animated series and films, with his last voice-acting credit being in the 2018 Teen Titans Go! To the Movies. Wheaton is also a huge video and board games fan, and he has his own YouTube gaming show called Table Top. He's been married to Anne Wheaton since 1999, and we don't see those two asking for some couples therapy any time soon. 

Κunal Νayyar & Neha Kapur

Kunal Nayyar's acting portfolio doesn't actually include many significant roles, but it seems that even a few have been enough to make him a millionaire. Prior to portraying Rajesh Ramayan Koothrappali on The Big Bang Theory, Nayyar was relatively unknown. After his success though, Forbes reported that he was among the top 3 highest-earning actors for 2015, with an estimated income of $20 million! Nayyar is now married to Neha Kapur, who's a household name in the Indian modeling industry. She won the 2006 Miss India beauty pageant, and the couple now lives in Los Angeles.

Melissa Rauch & Winston Beigel

Melissa Rauch portrayed Bernadette Wolowitz, Howard Wolowitz's wife on The Big Bang Theory. She joined the show's cast in 2009, and even if she hadn't landed many roles before that, the role of Bernadette gave an instant boost to her career and credit score. In 2010, she also managed to become a season regular in the popular series, True Blood. In the last couple of years, she mostly works as a voice actress, and she has even granted her voice to Harley Quinn in the animated film, Batman and Harley Quinn. Since 2007, she's been married to writer Winston Beigel, and in December 2017, the couple welcomed their first child.

LeVar Burton & Stephanie Cozart

You've surely heard of LeVar Burton, but definitely not from The Big Bang Theory, where he made just three guest appearances. Burton is famous for having hosted the kids show Reading Rainbow for over two decades, starting from the mid-'80s. He's also played Lt. Geordi La Forge on ST: The Next Generation. Burton has also directed several episodes for many different TV series, with his last work tracing back to 2017, when he directed three episodes of NCIS: New Orleans. Back in 1992, Burton tied the knot with makeup artist Stephanie Cozart, and they've been together ever since, having two children.

Matt Bennett & Liz Gillies

Matt Bennett became very popular when he starred in Nickelodeon's Victorious as Robbie Shapiro, while playing in Will Ferrell's The Virginity Hit made him even more famous and wealthy. When it comes to The Big Bang Theory, Bennett played Wolowitz's half-brother Josh in just one episode. Currently, he's starring in American Vandal, starting 2018, while he's also made guest appearances on Shameless and Grey's Anatomy, significantly increasing his popularity and earnings. His co-star in Victorious was Liz Gillies, and the two of them started posting several pictures on Instagram together, something that has led people into believing that they're together, though nothing's been confirmed yet.

Nathan Fillion & Krista Allen

Nathan Fillion made a single guest appearance on The Big Bang Theory portraying himself, but it was definitely not the first time you saw this guy on TV. Fillion has been one of the most successful TV actors of the past years, and his role as Richard Castle on Castle, from 2009 to 2016, made him super-famous (and super-rich as well, as he now sits on an $18-million net worth). In 2018, Fillion started appearing on The Rookie. Reportedly, he's been in a relationship with George Clooney's ex Krista Allen for two years now, with their fans wondering if they'll eventually get married. Fillion though is very secretive about his private life.

Sara Gilbert & Linda Perry

Sara Gilbert is no newbie when it comes to television. She got her first taste of stardom back in the '80s and the '90s, when she played in the iconic show, Roseanne. On The Big Bang Theory, Gilbert portrayed Leslie Winkle, and she appeared in nine episodes. In fact, Gilbert used to date co-star Johnny Galecki, when she realized she liked women. Today, she's been married to former 4 Non Blondes star Linda Perry, with whom she has three children (two from Gilbert's previous relationship). Gilbert is also the producer and co-host of the famous talk show, The Host, while she now stars in Roseanne's spin-off, The Conners.

Michael Trucco & Sandra Hess

Michael Trucco wasn't an important name on The Big Bang Theory's cast, as he made just one appearance, playing Dr. David Underhill, a physicist Penny had a crush on. Trucco is actually famous for having played on Battlestar Galactica and on How I Met Your Mother. Arguably, Trucco's acting portfolio is far from impressive, but he's still young and he's expected to appear in more shows and films. His latest acting credit was in the 2018 film Hunter Killer, where Gerard Butler starred in. Back in 2009, he married Sandra Hess, who's also an actress, but they still have no children. 

Keith Carradine & Hayley DuMond

Keith Carradine's name probably rings a bell to you. He comes from the Carradine family, which includes many renowned actors. Just like his father, John Carradine, Keith became a star, and nowadays, he's known for his roles on Nashville, Dexter, and Madame Secretary. He had a brief stint on The Big Bang Theory where he appeared for just three episodes. We last saw him on-screen in the 2018 film The Old Man & The Gun. Carradine is married to actress Hayley DuMond, who is actually much younger than he is. They met during the filming of The Hunter's Moon in 1997, but their wedding came nine years later.

Margo Harshman & Chris Marquette

Gorgeous Margo Harshman portrayed Alex Jenson, Sheldon's personal assistant who was madly in love with Leonard. She appeared on The Big Bang Theory from 2012 to 2013. Her next big role, which is also her most recent one, is the one on NCIS, where she played Delilah Fieldman, a paraplegic forensic, from 2013 to 2017. Harshman's brown hair and blue eyes never cease to amaze us, but she still has a long way to go before becoming a true celebrity, with her acting credits still being few. It is rumored that she's in a relationship with actor Chris Marquette, but for the time being, we don't know if that's true.

Brian Posehn & Melanie Truhett

Brian Posehn was another popular name on the Big Bang Theory cast. He portrayed Bert, a geologist, and he stayed in the show from 2013 to 2018. People also know Posehn from his role on The Sarah Silverman Program, though it's more possible that they recognize his voice, as he's voice-acted in a dozen of projects, such as Mission Hill and Captain Underpants: The First Epic Movie. We last heard him voice-acting in 2018, when he voiced Zeke in the animated series, Teachers.  After so many roles, his savings account is more than capable of supporting him and his wife Melanie Truhett. They married in 2004 and they have a son together.

Kevin Sussman & Alessandra Young

Stuart Bloom is one of the most hilarious characters on The Big Bang Theory, and he is portrayed by Kevin Sussman. Before landing his first roles, Sussman worked in many commercials. Nowadays, he's known for his role in the said show, as well as for having portrayed Walter on Ugly Betty. He's still acting in The Big Bang Theory, but other than that, he hasn't landed any new lucrative parts. He was married to Alessandra Young from 2006 to 2017 until they got a divorce. Sussman didn't stay single for long though, as, in 2018, it was reported that he started dating a woman named Whitney Rice.

Bob Newhart & Ginny Newhart

Bob Newhart is an absolute comedy legend. Starting as a stand-up comedian, Newhart grew to become one of the biggest names in deadpan comedy. He then hosted his own show called The Bob Newhart Show, while he also appeared and voice-acted in numerous movies and TV series. Newhart is now 89 years old, but retirement is definitely not in his plans yet. His latest role has been the one of Professor Proton on The Big Bang Theory, where he started acting in 2013 and appeared until 2018. He's married to Ginny Newhart. The couple tied the knot in 1963 and they now have four kids and ten grandchildren!

Jerry O'Connell & Rebecca Romijn

Jerry O'Connell is quite an experienced actor, and his career started way back in the '80s. Nowadays, he's mostly famous for having played in the TV series Sliders, while he's also appeared in popular films such as Jerry Maguire and Scream 2. His Big Bang Theory appearance is rather recent, as he appeared in the show for three episodes in 2018. Currently, O'Connell stars in Carter, which is his most recent TV role as well.  Even if he's not as relevant as he used to be back in the 2000s, O'Connell's salary is pretty high. In 2007, he married actress Rebecca Romijn, and they now have two daughters.

James Hong & Susan Hong

James Hong is a true acting giant and with over 500 acting credits, and indeed, his film and TV series portfolio is mind-blowing! He first came to prominence in the late '50s, when he starred in The New Adventures of Charlie Chan.  Since then, he's appeared in iconic films such as Bladerunner and Wayne's World 2, having also voiced numerous Disney characters. On The Big Bang Theory, he played Chan in two episodes back in 2007, and we last saw him on TV in 2018, when he appeared in an episode of Hawaii Five-0. Since 1977, he's been married to Susan Hong, with whom he has a daughter.

Kathy Bates & Tony Campisi

Kathy Bates is one of the most acclaimed actresses to have joined The Big Bang Theory cast. The year 2018 was rather lucrative for her, as she both appeared in three episodes of the said show, while she also landed her most recent starring role on American Horror Story: Apocalypse. Bates has played in popular movies, including Primarily Colors and About Schmidt, but her private life hasn't been that good. In 1991, she married Tony Campisi, and while they seemed perfect at first, they couldn't avoid getting a divorce in 1997. Bates hasn't remarried since.

Stephen Merchant & Mircea Monroe

Stephen Merchant appeared on The Big Bang Theory for just three episodes in 2015, but his run in the acting industry has been very fruitful. Gaining attention from his work with Ricky Gervais in the British series, The Office, Merchant capitalized on the show's success to become a household name in comedy, both on-screen and on-stage performances. He also co-hosted The Ricky Gervais Show on the radio, and he's won three BAFTA Awards, among other accolades. His most recent TV appearance was in 2018, in a Christmas-special called Click and Collect. He's currently dating Mircea Monroe, and his fans wonder if a wedding between those two is forthcoming!

Regina King & Ian Alexander Sr.

Regina's last name is "King," but you should better call her "Queen," as she's one of the most successful TV actresses ever. King has starred in 227 and Southland, while she's also received some pretty fat paychecks from her appearances in hit movies like Jerry Maguire. On The Big Bang Theory, King appeared five times, having portrayed Janine Davis. Her latest film was the 2018 romantic drama If Beale Street Could Talk, for which she won a Golden Globe Award for Best Supporting Actress. Back in 1997, she tied the knot with Ian Alexander. They had a son, born in 1996, but this wasn't enough to keep them together. They split in 2007.

George Takei & Brad Takei

George Takei wouldn't be absent from a show called The Big Bang Theory. Takei knew all about space back in the '60s, when he portrayed the iconic Hikaru Sulu on Star Trek: The Original Series. On The Big Bang Theory, he appeared in just one episode, playing himself. Takei is currently one of the most famous LGBT activists out there, always supporting their causes and using his high fame and credit score to promote social-rights campaigns. Since 2008, he has been married to a man named Brad Takei. In 2017, he was accused of indecent assault by former actor Scott R. Brunton, but it all ended up probably being a publicity stunt.

Billy Bob Thornton & Connie Angland

The Big Bang Theory has hosted some of the most legendary Hollywood figures from time to time, and in 2014, it was Billy Bob Thornton's turn to make a guest appearance in the hit show, portraying Dr. Oliver Lorvis. Throughout the past years, Thornton has earned many awards, including an Oscar, for his astounding performance in classics such as Sling Blade, Primary Colors, and Monster's Ball. He still rocks the screens, with his latest film appearance being the 2018 drama, A Million Little Pieces. However, his private life has been a real rollercoaster ride, as he's had to get five divorces before marrying for the 6th time; he married Connie Angland in 2014.

Elon Musk & Talulah Riley

Elon Musk can take pride in a lot of different things: sending a Tesla automobile to space in 2018, being the co-founder of PayPal, Tesla, and SpaceX, but most importantly, making a guest appearance on The Big Bang Theory! The mega-entrepreneur, who currently sits on a breathtaking $22.4-billion net worth, appeared in the said show in 2015, portraying himself. While his business ventures have been the most talked-about thing recently, his romance with actress Talulah Riley was kind of a fiasco. They married in 2010, then divorced in 2012. They remarried in 2013, and in 2014, they were on the brink of splitting again. Eventually, they split for good in 2016.

Mark Harelik & Spencer Kayden

Mark Harelik's acting career has been very rewarding, even if he's not actually considered a celebrity. That's probably why he's mostly appeared in stage-plays, but his on-screen portfolio is actually rather impressive. Having played in films such as Jurassic Park III and 42, Harelik has also landed roles in some very popular series like Seinfield and NCIS. He played on the first 21 episodes of The Big Bang Theory, portraying Dr. Eric Gablehauser. In 2018, he appeared in an episode of How To Get Away With Murder. Since 2004, he's been married to actress Spencer Kayden, with whom he has acted in many stage productions. They have one child.

Dean Norris & Bridget Norris

Dean Norris first found success as an actor back in the '90s, when he played in films like Lethal Weapon 2 and Terminator 2: Judgement Day. As the 2000s went by, he mostly landed roles on TV series. It all changed when he portrayed DEA agent Hank on Breaking Bad, his most lucrative and famous role until now. Since then, his earnings have skyrocketed, and he currently stars on Claws, while he also makes occasional appearances on The Big Bang Theory as Colonel Richard Williams. He's been married to Bridget Norris since 2001, and apart from having five kids, in 2018, they founded the Norris Performing Arts Center, located in Temecula.

 Joshua Malina & Melissa Merwin

Joshua Malina was much more relevant back in the '90s when he played in films like A Few Good Men and The American President. However, that doesn't mean that he doesn't get some fat paychecks anymore, as he's still very active in the industry. On The Big Bang Show, which is also Malina's most recent TV role, Malina has been playing President Siebert since 2011. He's also famous for having spent eight years in the cast of Scandal. Malina met his wife Melissa, a costume director, back in the early '90s, and they wed in 1996. Since then, they have welcomed two children and have been inseparable.

Stephen Root & Romy Rosemont

Another experienced actor who joined The Big Bang Theory cast was Stephen Root, known from films like Dodgeball and Get Out. He played Dan in two episodes, back in 2014. His TV-roles portfolio includes starring roles in Star Trak: The Next Generation and Office Space, with his latest TV role being in the 2018 series, The Man in the High Castle. Root's wife is actress Romy Rosemont, whom he married back in 2008. It is his second marriage, and he has a son from his previous one. They probably felt great when they both made a guest appearance on Fringe in 2011.

DJ Qualls & Nikki Reed

DJ Qualls has portrayed some of the most hilarious nerdy characters, and one of them was the role of Toby Loobenfield, which he played in one episode of The Big Bang Theory in 2007. Qualls has had significant earnings all these years, having played in numerous hit series such as Breaking Bad and NCIS, while he has been starring in The Man in the High Castle since 2015. Back in 2006, he was all over the tabloids' front page, as he started dating Twilight Saga star, Nikki Reed. Their fans were quickly disappointed though, as their romance lasted just for one year!

Josh Brener & Meghan Falcone

Josh Brener is mostly famous for having starred on Silicon Valley, but he did have a 2-year period on The Big Bang Theory, where he portrayed Dale. He's also appeared in TV series like Glee and The Middle. Brener is now 34 years old, and since the last couple of years, he's been making money mostly by working as a voice actor in animated films and series such as Star Wars: Resistance. He's been in a long-term relationship with actress Meghan Falcone, and the couple has recently listed their Hollywood Hills mansion for a cool $1.42M!
