When The Big Bang Theory dropped in 2007, it was just four nerdy friends and their hot, clueless neighbor. Flash forward to today, and it turned into a groundbreaking sitcom—diving into everything from love to life’s big questions.

The on-screen duo, who played the lovable Leonard and Penny, had undeniable chemistry from the get-go. But it was a particularly steamy scene in an elevator that sent shockwaves through their real-life relationship. In an exclusive interview with Variety, Kaley Cuoco spilled the kind of tea that’s hotter than Sheldon Cooper’s obsession with comic books.

I was very nervous with both [the on-screen and real-life first kisses]. I mean, I was kissing him as Penny before we ever dated, and it’s weird when you have a crush on someone and you’re kissing them as actors. It was an enjoyable experience for me.  

Even Johnny Galecki was a blushing mess, admitting he felt a little tingling during the scene. The actor confessed, giving us all major heart-eye emojis:

We felt something, yeah. I think that was a massive turning point [in our relationship]. At that point, both she and I knew that something mutual was felt, and that it was going to be more of a distraction from the work to try and continue to ignore it than to actually recognize it and surrender to it.

They dated for two years, with their on-screen romance mirroring their real-life love. Even after breaking up, their strong friendship endured. While their characters married on-screen, their real-life journey—full of highs and lows—is the ultimate heartwarming twist.
