Oops She Did It Again! Britney Spears walked off the set of the X Factor after another contestant sang one of her songs. This time one of the contestants sang the song, (You Drive Me) Crazy, and BritBrit looked stunned throughout the performance. Even co-judges Demi Lovato and Simon Cowell tried to keep their faces covered to hide their reactions. The contestant was a man dressed as a scantily clad woman, including a bedazzled jean jacket! Later Britney returned to the table and said, "I really respect the tribute...It was really nice." Haha! (Source: people)
