London: Barbadian singer Rihanna celebrated her 23rd birthday with a risque performance at the NBA All-Star game that left many shocked.
The singer, who turned 23 on February 20, sang to an audience filled with celebrities, and families, the Daily Mail reported.
She was seen cavorting on stage in a skimpy outfit, and at one point even grabbing her crotch in full view of the crowd.
Rihanna wore a crystal-covered basque and fringed hotpants and accented the outfit with fishnet stockings to finish off her look.
She performed a medley of her hits to close out the annual basketball event, and was also joined by Kanye West and Canadian rapper Drake.
