Kaley Cuoco recalls filming awkward Big Bang Theory sex scenes with ex-boyfriend Johnny Galecki

Actor was convinced show bosses added more sex scenes only after she and Galecki broke up

Kaley Cuoco has reflected on filming Big Bang Theory sex scenes with her ex-boyfriend and co-star Johnny Galecki.

Cuoco and Galecki, who portrayed Penny and Leonard on the long-running sitcom, were a real-life couple towards the beginning of the series, and then became a couple on the show as well.

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

Cuoco did note, however, that she became convinced that the show’s creator Chuck Lorre wrote in a raft of sex scenes between Penny and Leonard to “f*** with” the two stars, who had just broken up in reality.

“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,” Cuoco recalled.

“Johnny and I talk about it and I think [Chuck] did that on purpose just to f*** with us,” she continued. “Because that came out of nowhere. All of a sudden these characters were all up on each other.”

Galecki and Cuoco regularly mock one another on social media, with Galecki recently joking that he was too busy to pay attention to Cuoco’s new series.

On her Instagram show, titled Cup of Cuoco, the actor teased that she would be unveiling secrets from her forthcoming Big Bang Theory follow-up The Flight Attendant.

Cuoco wrote: “Tomorrow and Tuesday, I am very excited – I will be dropping tons of Flight Attendant information. Yeah lots.”

Galecki wittily responded: “I’m busy Tuesday,” and Cuoco – proving the pair are still friends – replied with the laughter emoji.
