Watch Nick Youngerman Sing Ke$ha’s “Tik Tok” in His X Factor Judges’ House Performance on October 10, 2012 (VIDEO)
Nick Youngerman totally impressed Britney Spears enough that she danced (like your dad) to his Vanilla Ice cover. In his Judges' House performance of Ke$ha's "Tik Tok," the feelings were a little less jubilant. Demi Lovato said, "I couldn't tell if I was loving it or super annoyed by it" but Nick Jonas said he "thoroughly enjoyed" the performance. Your call.
