The 41st Annual People's Choice Awards - Press RoomOnly weeks after "The Big Bang Theory" star Kaley Cuoco announced her divorce from husband Ryan Sweeting, the actress has been beset by rumors of a rekindled romance with her "TBBT" co-star -- and former boyfriend -- Johnny Galecki. Now, Cuoco has taken to Instagram to shut down that talk once and for all.

This week, Cuoco shared a sweet black and white snap of her and Galecki sitting on a bench together, smiling and giving each other a fist bump. And while the image may make some 'shippers excited, the actress's caption confirmed that this relationship is strictly platonic.

"So sorry to disappoint, but no home wreckers or secret flings going on here," Cuoco wrote. "Me and @sanctionedjohnnygalecki are just the best of buds - Leonard and Penny will just have to suffice!"

Cuoco and Galecki's onscreen alter egos, Penny and Leonard, just tied the knot on the long-running CBS sitcom, after years of on- and off-again dating. Sadly for "TBBT" fans, it doesn't look like that will happen for their real-life counterparts anytime soon -- or ever.

Cuoco's rep confirmed the actress's split from Sweeting late last month, after 21 months of marriage. The pair had a whirlwind courtship, getting engaged in September 2013 after only a few months of dating, and marrying in December 2013.
