Rihanna's working birthday
With a celebrity-studded crowd looking on, Rihanna rocked the half-time show at the NBA All-Star game on her 23rd birthday.
She had some other big names helping her sing her hits on Sunday, with 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 half-time, the lights inside Staples Centre 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.
