Britney Spears blew everyone away during her Vegas debut last night ... everyone, but Katy Perry . Katy was front and center for the " Piece of Me " show -- rubbing elbows with Miley Cyrus and Adam Lambert. Miley danced away, while Katy seemed less than interested. Britney's certainly no John Mayer , but the pop singer's dancing skills have attracted more than a few rave reviews.
