Chris Brown Girlfriend: Karrueche Tran Celebrates Labor Day Weekend Vegas-Style

Chris Brown celebrated big this Labor Day weekend: the hip-hop star performed a smash set at Las Vegas' Hard Rock Hotel and Casino Saturday night before hitting up Diddy's huge surprise bash at the Paris. Then on Sunday Brown made an appearance at a star-studded pool party that took place at club Rehab, where Christina Milian and DL Pauly D were spotted. And looks like Brown's current beau, model Karrueche Tran, went along for the wild Vegas ride, posting fun and impromptu Instagram pics on Twitter throughout the weekend.
