Are Kaley Cuoco and Sam Hunt dating?

It's unclear, but the two were seen leaving a Grammys after-party together on Monday night.

Country newbie Hunt and the "Big Bang Theory" actress were spotted leaving Hyde nightclub in Hollywood, though no one saw any PDA.

Still, a source told E! News that there was definitely some flirting going on.

"She was really happy, you can see it," an eyewitness told E! "It looked like they completely hit it off and were trying to downplay the flirtation as friendship but it was pretty undeniable. Kaley kept talking to him with her hand over her mouth."

Cuoco separated from husband Ryan Sweeting in the fall and has been single ever since. She sparked rumors that she was getting back together with ex-boyfriend and "Big Bang Theory" co-star Johnny Galecki when the two were spotted cuddling at the People's Choice Awards in January, but she brushed off the speculation with the hashtag "#notdating" on an Instagram post.
