Cuoco, 30, and Galecki, 40, who star as Penny and Leonard on the hit CBS show, split in 2010 after secretly dating for two years. Rumors that the two got back together came to light after Cuoco announced she was divorcing her husband, Ryan Sweeting, in September. Cuoco slammed the romance rumors for the first time back in October, captioning an Instagram pic, "So sorry to disappoint, but no home wreckers or secret flings going on here. Me and @sanctionedjohnnygalecki are just the best of buds -- Leonard and Penny will just have to suffice!"

ET caught up with Galecki backstage, where he opened up about the blurry pic he posted on New Year's Eve, which featured him kissing a mystery blonde.

"Oh, I just thought it was a beautiful photo," he told ET. "That's all. It was New Year's Eve. It was jittery and we were being jostled by the crowd."

Cuoco chimed in, saying, "OK, let's be honest about what's going on here. It was Melissa [Rauch] and Johnny at New Year's Eve together. Just give it up."

Well, that settles that!

Though she isn't a fan of talking about her own dating life, Cuoco and her sister, Briana, are obsessed with watching Ben Higgins' journey to finding love on season 20 of The Bachelor. She couldn't stop gushing over the dating show while chatting with ET backstage.

"[My sister and I] tried to get through to Bachelor Live [the after show hosted by Chris Harrison] and I was cut off, I would like you all to know!" she shared. "I called in to ask my questions that the fans supposedly get to call in and ask, and I was not allowed to. I'm just putting it out there. So, Ben Higgins, I have questions for you, and I will save my questions until I get through and I will be on my phone when I get in my car to try and get through tonight."
