Katy Perry let her animal side shine at Sunday night's VMAs in Brooklyn. First, she hit the red carpet in an embellished Emanuel Ungaro dress (complete with a grill) and later closed the big show with a standout performance of her new hit single, "Roar," under the Brooklyn Bridge. It was Katy's first time performing at the VMAs since 2009, and she definitely made a triumphant return. The star put on a Rocky-themed show in a full-scale boxing ring, baring her belly in a printed sports bra and silk shorts, and was surrounded by giant gold tigers as she "roared" under the illuminated bridge. The upbeat song has already hit a record for the pop star, as it gave Katy her biggest digital-song sales week ever.
