Has Kaley Cuoco gone back to the arms of an old flame? That's what fans can't help but wonder as the Big Bang Theory star was spotted getting up close and personal with her co-star and ex-boyfriend Johnny Galecki at the People's Choice Awards in Los Angeles on Wednesday night.

What's more, both Cuoco and Galecki shared a handful of photos of each other backstage at the awards show. The blond beauty shared a pic of her giving Galecki a smooch on the check and captioned it with, "Thank you for the @peopleschoice award!! Look how happy we are!! @bigbangtheory_cbs season9 #mydate #notdating".

Some of her followers commented on the pic with, "Not dating she says, but they're all up in each other lol," along with, "I think you guys belong together."

Another fan wrote, "Hahaha brilliant hashtags good work calming the rumor mill. Gotta admit though still wish it was real!"

Cuoco recently pulled the plug on her marriage to former tennis ace Ryan Sweeting back in September after being married for less than two years. Before that, Cuoco and Galecki dated for two years until December 2009, around the same time their characters Penny and Leonard began their relationship on the show, too.

The Big Bang Theory airs Thursday on the CBS network.
