Lady GaGa donned a metallic outfit matched with a pair of devil horns when singing on U.K. talent show "The X Factor" Sunday, December 6. Performing "Bad Romance", she did not only appear with those outrageous costumes but also had bizarre set which featured a giant bath and shower and included a troupe of dancers in zombie-style white outfits.

The dance queen also took time to give advice for the show's contestants saying, "Be yourself!" She then added, "Don't let anyone ever tell you that you can't achieve your dreams."

When agreeing to perform on "X Factor", Lady GaGa reportedly had odd requests, demanding lambs and butterflies for her on-stage act. "He [Simon Cowell] thought the animals request was a joke but then realized it was Lady GaGa. Simon is an animal lover and wasn't against having the lambs running around, but he said no because of health and safety," a source told The Mirror.

In addition, Lady GaGa was rumored requesting closed set for her rehearsals, which was also asked by Janet Jackson who delivered a medley of her old material "All for You" and a new song called "Make Me" on the show.
