The Big Bang Theory: Real-Life Relationship Status, Age, Height & Zodiac Of The Main Cast
As Sheldon, Leonard, Penny, and co., the cast of The Big Bang Theory made audiences laugh for over a decade. Get to know these talented sitcom actors.

The Big Bang Theory gave fans 12 incredible seasons before wrapping up in 2019. The cast of the CBS sitcom grew a new following as they brought their characters and their love of science and friendship to life. Since the show’s ending, the actors have dove headfirst into new projects and a life outside of The Big Bang Theory world.
Over on Instagram and Twitter, the cast has been very open about their current projects and life outside of acting. And since it’s been two years since the show’s ending, fans can’t get enough of the new paths these stars are taking. From family life to a new view behind or in front of the camera, the incredible actors and actresses who gave us Sheldon, Leonard, Penny, Howard, Amy, Raj, and Bernadette are still as much desired today as they were in season 1 of TBBT.
Johnny Galecki: Single, 40, 5’5″, Taurus
Johnny Galecki is one of the few child stars who continued thriving in Hollywood without much controversy. He was one of the first actors cast in The Big Bang Theory and was a main part of the show since his character lived with Sheldon and crushed on Penny.
Standing at 5’5″, Galecki is now the father of a son, Avery, whom he welcomed with his ex-girlfriend Alaina Meyer. And as a Taurus born in April, Galecki enjoys his downtime and spending his days with his son.
Jim Parsons: Married, 47, 6’1″, Aries
Jim Parsons was the tallest member of the group in The Big Bang Theory standing at 6’1″. While his character Sheldon married Amy Farrah Fowler in the 11th season, Parsons has been married to his husband Todd Spiewak since 2017 after being together since 2002.
At 47 years old, Parsons has kept himself busy in the world of TV. He’s one of the minds and voices behind The Big Bang Theory‘s spinoff, Young Sheldon, and is the executive producer behind Mayim Bialik’s new show, Call Me Kat.
Kaley Cuoco: Married, 35, 5’6″, Sagittarius
This feisty Sagittarius is only 35 years old and making an incredible career for herself in Hollywood. After Kaley Cuoco’s success as Penny, she dove into the animated show Harley Quinn as the titular antiheroine. More notably, Cuoco was just nominated for a Golden Globe for her work in the TV series she starred in and produced, The Flight Attendant. Outside of filming, Cuoco has been married to her equestrian husband, Kal Cook, since 2018.
Kunal Nayyar: Married, 39, 5’7″, Taurus
Kunal Nayyar did a fantastic job of bringing Raj’s insecurities to life. However, Nayyar has more to offer than an astrophysicist who’s afraid to talk to women. Since the show, the 5’7″ actor has been a part of Think Like a Dog, Trolls World Tour, and is currently filming a new TV series called Suspicion.
And while Raj didn’t find love on the show, Nayyar has been married to model, actress, and beauty queen, Neha Kapur, since 2011. As a Taurus, Nayyar and co-star Johnny Galecki likely have very similar temperaments and interests.
Simon Helberg: Married, 40, 5’4″, Sagittarius
Out of the men in The Big Bang Theory, Howard Wolowitz is the shortest and makes his stature part of his hilarious shtick. Standing at 5’4″, Simon Helberg took some time off from acting after the show wrapped and produced a TV documentary called Elvis Goes There. However, his IMDb page shows that he has two new projects in the works.
Like his character Howard, Helberg is a married man, having wed actress Jocelyn Towne in 2007. The couple has two children together. One would imagine that fellow Sagittariuses Helberg and Kaley Cuoco have very similar personalities.
Melissa Rauch: Married, 40, 4’11”, Cancer
Just like her on-screen husband, Melissa Rauch is the shortest of the ladies at 4’11”. At 40 years old, Rauch is married to producer Winston Beigel and has two children with him. Among Rauch’s costars, she’s the only Cancer in the group with a birthday in June.
Cancers are warm and loving individuals with a passion for adventure. Rauch’s adventurous spirit has landed her in projects like The Laundromat, Robot Chicken, and Cats & Dogs 3: Paws Unite since the ending of The Big Bang Theory.
Kevin Sussman: Dating, 50, 5’8″, Sagittarius
Kevin Sussman didn’t become a main character on The Big Bang Theory until later seasons but he was still a huge secondary player in the series. As the comic book owner, Stuart was a part of the gang’s hilarious conversations and weekend plans.
In real life, Sussman is a well-accomplished actor. The 50-year-old divorced Alessandra Young in 2017 and has since been dating Addie Hall. Standing at 5’8″, Sussman doesn’t have any upcoming projects according to his IMDb profile, but he’s made quite an impression on TBBT fans.
Mayim Bialik: Single, 45, 5’4″, Sagittarius
Mayim Bialik played everyone’s favorite, Amy Farrah Fowler. Like the woman she was portraying, Bialik also had her Ph.D. in neuroscience. And just like Kaley Cuoco, Simon Helberg, and Kevin Sussman, Bialik is also a Sagittarius!
The 45-year-old has been divorced from Michael Stone since 2012 but the former couple has two sons together with whom they co-parent nicely. Standing at 5’4″, Mayim is now starring in a new TV series called Call Me Kat and has been announced as a voice in The Inspector Chronicles.
