Following an introduction from Brandy, Swizz Beatz turned the American Music Awards into an all-out dance party during his exhilarating set at Sunday’s show. As women bum-rushed the stage, Swizzy performed his dance-floor anthem “Everyday Birthday” in celebration of the 40th anniversary of the AMAs.

Chris Brown worked up a sweat as he showed off his fancy footwork, stripping shirtless before dancing in the aisles. Fresh from Europe where he was shooting Fast and Furious 4, a dapper Ludacris also joined the festivities.

Report to the dance floor.
