Mean Girls!

Paris Hilton could be the ultimate "Mean Girl." The celebutard apparently ditched her erstwhile "best friend forever" Kim Kardashian for Britney Spears because, one L.A. wag sniped, "[Kardashian] got shined for the more popular girl." Not one to stay home and cry, Kardashian hit the MTV 24/7 party at Area the other night with fellow D-lister Brittny Gastineau. Meanwhile, Spears hit the Hollywood Roosevelt with Brandon "Greasy Bear" Davis. They got along so well, our spy even caught them in the bathroom together.
