LOS ANGELES, Oct. 1 (UPI) -- U.S. actress Kaley Cuoco says she dated Johnny Galecki, her co-star on "The Big Bang Theory," but it was a secret neither of them ever spoke publicly about.
"We dated for almost two years. It was such a huge part of my life and no one knew about it," Cuoco told CBS Watch Magazine. "This is the first time I've ever talked about it, ever. It was a wonderful relationship, but we never spoke a word about it and never went anywhere together."
