"X Factor UK" Contestant Jahmene Douglas proved the old saying "Don't judge a book by it's cover" the other night when he SHOCKED the crowd and the judges with his cover of "At Last" by Etta James.

By all accounts, it looked like Jahmene was seriously going to stink it up. Turns, out, he was really just VERY VERY nervous. Skip ahead to the 2:00 mark to get blown away. He ain't singin' country, but the boy is SINGIN!
