It’s Britney, Bitch: Britney Spears Takes Las Vegas
She's baaaaaaack. Last night at the Planet Hollywood Resort & Casino in Las Vegas, Britney Spears kicked off her "Britney: Piece of Me" residency in front of a crowd that included her little sis Jamie-Lynn, Miley Cyrus, Katy Perry and Mario Lopez (who Brit walked around on stage on a leash). Click through to see a dozen sort of awkward photos of the pop star performing. A Frisky staff roadtrip to Vegas is so necessary.
