Diddy dove into the party spirit, taking swigs of vodka straight from the bottle.
The hip-hop mogul hosted the celebration at The Palms, a trendy hotel in Las Vegas.
He took control of Palms Pool, a sprawling two-acre outdoor oasis at the venue.
Dressed in a bold pink T-shirt, the American star gave a nod to the French vodka brand Cîroc as he climbed onto the stage.
Joining him was fellow rapper Akon, who showed up in an all-white ensemble.
The event, held over America’s Labor Day weekend, also welcomed Christina Milian as one of the star-studded guests.
