The 2010 American Music Awards happened on Sunday (Nov 21) in Hollywood and as always was jam packed with today’s hottest stars.

Rihanna opened the show with a hip-gyrating performance of her current chart-topping hits “What’s My Name?” and “Only Girl (In The World)“.  The pop diva, who was awarded the Best Soul/R&B Female Artist award, was seen hanging out at My Studio night club right after the show, wearing the same gorgeous pale green dress she accepted her award in that night.

In addition, Christina Milian was also spotted at another party showing off her killer legs, as well as “Pretty Girl Rock” singer Keri Hilson.
