"In all the scenes before we met, something was always there. It was love at first sight. Cuoco admits she was "very nervous" during the first season before they met "Halloween episode kiss.

"I was kissing him as Penny before we dated, which is weird," she says. It took months for the two to kiss off camera, but Galecki soon realised they had chemistry.

Cuoco and Galecki filmed a dream sequence in Season 1's "The Nerdvana Annihilation" Leonard saves Penny in the elevator shaft.

Cuoco: "It wasn't fun."

Galecki: "We had to be in each other's arms for a while because it was a stunt." "That was definitely a moment—"

Cuoco: "We fell in love in that elevator shaft."

"Definitely. That was a turning point in our relationship. At that point, we both knew that something mutual was felt and that ignoring it would be a distraction from the work "Confirms Galecki.

Cuoco eventually broke up with her boyfriend and joined Galecki and the cast in Montecito, Calif. The actress called Galecki to her cabin to kill a bug.

"To this day, I don't know if this story is true or if she was flirting with me because she'd just broken up with her boyfriend, but I didn't go to her cabin," Galecki says.

"I flirted with a bug in my room. Both true! I thought, This could get him in! However, "Laughing Cuoco. "He rejected me! I think he turned me down because he knew my plan. He didn't come over despite my bug excuse."

Nobody was surprised when the actors told the cast and crew. "Kaley and I considered marrying," Johnny Galecki says, but his need for privacy led to their breakup.

"We're from different worlds, but we seem to blend in. When I wanted different things, it made things more complicated "Explains Galecki.

"My strict privacy policies and Kaley's openness contributed to our rift. I was uncomfortable going public with it, and I think that hurt Kaley's feelings "Continuing, "It wasn't because I was embarrassed of her or our relationship, but I wanted to protect Penny and Leonard from tabloids."

Galecki: "It made me uneasy because we were working together and the show's viewership was growing. It felt like we were living a lie because we went to award shows and functions pretending we weren't a couple, when we were a loving couple."

Galecki says they "had very different interests in what we wanted from life," but they remained close after the split.

"We're great friends. I value my relationship with her above all others "Sharing.

Cuoco didn't dispute his take, but added context.

"Johnny and I ran out of things to talk about because we worked all day and then asked, "How was your day?" Simon's funny, right? We'd laugh because there's no mystery "Recalls.

"But we stayed together. We loved each other and were lucky that there was no foul play in our breakup; it just ended "Continued Kaley Cuoco. "Yes, we were hurt, but we were friends again quickly. He was in both of my weddings' front rows, and we've been so supportive since. We're sweethearts."

Galecki is private. The actor and model split in 2020. One son is shared. Tom Pelphrey is Cuoco's boyfriend. They walked the 2022 Emmys red carpet together, so they don't mind being open.
