Sara Gilbert and Johnny GaleckiFormer 'Roseanne' co-stars Sara Gilbert and Johnny Galecki were reunited today on 'The Talk,' and Gilbert's co-hosts pumped him for gossip. Specifically, Sharon Osbourne wanted to know if Galecki ever had a crush on Gilbert and if he ever dated her.

Galecki admitted to having a crush, but turned to Gilbert to see whether she would technically call what they did "dating."

"Sara's a very good kisser," he said. "I was more nervous about our kiss on 'Big Bang Theory' than I was on 'Roseanne' or even, previous to that, in personal life because you're the only person who can gauge if I've improved as a kisser over the last 20 years." Watch the video after the jump.
