Kaley and Johnny dated!
Kaley Cuoco and Johnny Galecki played a Cheesecake Factory employee and aspiring actress named Penny and an experimental physicist named Leonard, who soon fell in love with each other after a couple of episodes. Turns out, Cuoco and Galecki were also dating in real life, and their co-stars and staff had no idea about it! They dated for two years and split up in 2009, but remained good friends and co-workers. “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. But that also made it sad, too,” Cuoco admitted to CBS.
