Well this is awkward!

Jerry Seinfeld was caught off guard when he was approached by Kesha on the red carpet of the Night of Laughter & Song at the Kennedy Center last night, and the comedian rejected her request for a hug because he didn't know who she was, nor did he care once he found out!

The "Tik Tok" songstress ran up to him and said she "loves him so much", but when she asked for an embrace, he wasn't having it. "No thanks, no thanks, no thanks," he said while backing away from her. Ouch!

The only person who would have made this more uncomfortable would have been Larry David!
