Katy Perry was one of the celebs on hand to watch Britney Spears’ Vegas debut of her new show, ‘Britney: A Piece of Me.’ Katy kept her look casual for the show, which makes sense: she was just hanging out in the audience. I wonder if John Mayer came with her? I haven’t seen any pictures of him at the event. According to TMZ, Katy wasn’t looking all that impressed during the show.
Katy was front and center for the “Piece of Me” show — rubbing elbows with Miley Cyrus and Adam Lambert — and while Miley danced her ass off, Katy couldn’t seem less interested.
