Mayim Bialik and Johnny Galecki Recreate Their First On-Screen Kiss From 'Blossom' Days
By Jackie Willis
Kaley Cuoco isn't the only Big Bang Theory star who has a history with Johnny Galecki.
The cast of the hit CBS show appeared altogether on Wednesday's Conan, and things got a little awkward when the host brought up Mayim Bialik's on-screen kiss with Galecki when they were both on the hit '90s sitcom, Blossom.
It's no secret that Galecki and Cuoco dated when Big Bang Theory first started, but after the actress announced her split from husband, Ryan Sweeting, a new crop of romance rumors spread about the co-stars. "So sorry to disappoint, but no home wreckers or secret flings going on here," Cuoco responded via Instagram to the reports in January. "Me and @sanctionedjohnnygalecki are just the best of buds -- Leonard and Penny will just have to suffice!"
