Jerry Seinfeld explains why he refused to hug Kesha

In a new interview, Jerry Seinfeld stands by his decision to turn Kesha down cold for a hug - three times! The comedian unintentionally got people laughing this week by refusing a hug from Kesha on the red carpet at A Night of Laughter and Song at the Kennedy Center in Washington, D.C., Monday. He was giving an interview when the "Tik Tok" singer broke in, and, well, by now you what happened. "I'm 63, I don't know every pop star," Seinfeld explained to Extra on Thursday. "I don't know everyone." He added, "I was right in the middle of an interview, it was a little off."
