Singing sensation Rihanna celebrated turning 23 with one of her trademark racy performances.
Known for her sensual stage act, the singer went for maximum impact during half-time at a basketball game on Sunday
During the performance, she gyrated her hips dressed in a barely-there leotard.
Rihanna later joined the audience, covered up in jeans and a sweater.
Also attending the game were Jay-Z and wife Beyonce, who was decked out in sparkly seven-inch Christian Louboutin heels.
