Penny dated Leonard IRL on the DL

One of Kaley Cuoco’s longest relationships was the one she kept secret. In 2010, the actress dropped a bombshell when she revealed to CBS Watch that she dated co-star Johnny Galecki, who plays Dr. Leonard Hofstadter, for nearly two years. “It was a wonderful relationship but we never spoke a word about it and never went anywhere together. We were so protective of ourselves and the show and didn’t want anything to ruin that,” she said.

Cuoco claimed their incognito lifestyle eventually tore them apart. “We couldn’t do anything. It wasn’t as fun as we wanted it to be,” she said. “Everyone was always asking, and we deny-deny-denied. And I’m like, ‘Why am I denying this person that I love?’ It took a little bit of a toll on me and I think it did for him, too.”
