Kaley Cuoco Opens Up ABout Filming Big Bang Theory Sex Scenes With Co-Star & Ex-Boyfriend Johnny Galecki

Kaley Cuoco found it tough to film sex scenes with her ex-boyfriend Johnny Galecki on The Big Bang Theory.

The former couple began dating at the beginning of their time on the CBS sitcom — where Kaley played Penny, and Johnny played Leonard — and “fell madly for each other”, but split up two years later.

Speaking to Dax Shepard's Armchair Expert podcast, Kaley — who is now married to American equestrian Karl Cook — said: “We dated really early on for almost two years. When we did the pilot, I was crushing so hard on Galecki but he had a girlfriend.

“We got together and just fell mad for each other for two years, but then we broke up. Luckily Johnny and I came out of it so brilliantly and we’re closer today than we ever were.”

Although they remained close friends, their breakup coincided with the show’s creator, Chuck Lorre, developing the on-screen romance between their characters - who eventually got married - including adding more sex scenes.

And Kaley, 34, has said she found it “sensitive” to film those scenes, because their breakup was so fresh.

The actress recalled: “When we broke up obviously it was a little sensitive for a minute, but I remember those weeks that Chuck had written these episodes where all of a sudden our characters were like sleeping together every other second.”

Looking back on it, Kaley and Johnny — who's been with model Alaina Mayer since 2018 and has 11-month-old son Avery with her — can both laugh off the awkward tension between them, and even think Chuck added the scenes “on purpose” just to mess with them.

Kaley quipped: “Johnny and I talk about it and I think [Chuck] did that on purpose — just to f*** with us. If I was with him, I would ask him because that came out of nowhere. All of a sudden these characters were all up on each other."

Kaley will next be seen in the HBO Max series The Flight Attendant, premiering on HBO Go on Nov 26. In the series, she plays an alcoholic stewardess who wakes up in a Dubai hotel with her one-night stand next to her in bed — dead. In a Hollywood Reporter interview, she said she was too afraid to take a break after The Big Bang Theory ended. "You're easily forgotten, too," she said. "You've got to stay relevant. But also know when too much is too much. It's kind of a fine line. — BANG
