With a celebrity-studded crowd looking on, Rihanna rocked the halftime show at Sunday's NBA All-Star game in Los Angeles on her 23rd birthday.

She had some other big names helping her sing her hits, with Canadian rapper Drake joining in on What's My Name? and working "happy birthday" into the lyrics. Dripping in gold chains, a red-clad Kanye West came out for All of the Lights.

At halftime, the lights inside Staples Center went out and the video screens filled with water droplets, setting the stage for Rihanna to emerge from behind a wall singing Umbrella.

While it was a working day for Rihanna, her fellow music stars relaxed in their seats while watching the 60th annual All-Star game.
