No wonder Penny and Leonard had so much chemistry on “The Big Bang Theory.”
Kaley Cuoco, who portrays Penny on the show, recently revealed to CBS Watch Magazine that she and co-star John Galecki once dated.
"We dated for almost two years,” she said. "It was such a huge part of my life and no one knew about it.”
Cuoco said the pair went so far as to deny they were together. "This is the first time I've ever talked about it, ever,” the actress said. “It was a wonderful relationship, but we never spoke a word about it and never went anywhere together."
And now, like their TV counterparts, they are just friends.
"We knew we weren't destined to be together,” Cuoco said. “We accepted it and said, 'Look, if we ever break up, we will be professional. I'm so lucky it was a mutual ending and that we don't hate each other. We've seen that happen on other shows.”
