Chris Brown partied his tail off — and apparently his shirt too — as he celebrated his birthday last night (May 6) at Club Play in Miami Beach. Lil WayneTrina, and a few others were also spotted in the building.

Next stop: Sin City! Chris is scheduled to head to Las Vegas tonight to celebrate his birthday once again at PURE nightclub where the 22-year-old will be joined by close family and friends.

Check out the pics from last night in Miami below:
