The Big Bang Theory actors just revealed which cast member had sex in their dressing room, because this is vital information

After 12 seasons of Rock, Paper, Scissors, Lizard, Spock, The Big Bang Theory has officially come to an end. The series finale aired last night, May 16th, leaving fans with surprising endings for Penny, Leonard, Sheldon, and the rest of the gang. And even though the show is over, there are still plenty of behind-the-scenes details to be shared. In fact, after the finale, Johnny Galecki, aka Leonard Hofstadter, revealed that he once had sex in his dressing room

The admission came during a cast appearance on The Late Show with Stephen Colbert. Colbert asked the group if any of them had ever, uh, done it, in their dressing room. Kaley Cuoco burst out laughing and immediately turned to Galecki.

"You must have," she said to him, with Kunal Nayyar agreeing.

Galecki initially tried to brush off the accusation but ultimately fessed up, sheepishly raising his hand. Cuoco, who, according to Today.com, secretly dated Galecki for about two years, was quick to clarify, “that did not include me.” Simon Helberg, who plays Howard Wolowitz, joked, “We all used Johnny’s dressing room.”

Watch the clip below.

Other highlights from the segment include Galecki sharing what animal Cuoco would be (an “Arabian pretty horse”) and Melissa Rauch (aka Bernadette) saying that she would be a cook if she weren’t an actress.

We’re so sad to see The Big Bang Theory go, but we’re looking forward to more behind-the-scenes revelations. Plus, there’s always reruns…
