24 year-old Rihanna is serving it tonight at the 2013 Grammy Awards Show at the Staples Center in Los Angeles, as she stunts in a Alaia design gown. Check out the pics below:

Rih rocked the hell out that dress, and it's said to be nominated in the "Best Dressed Category" on Fashion police.

Hollywood's cute couple, Amber Rose, who's rocking Donna Karan, was spotted on the red carpet with her baby daddy/rapper Wiz Khalifa, who rocked a black and white suit.

R&B crooner Frank Ocean, who's nervous about performing at tonight's Grammys, was spotted on the red carpet with his broken finger.

Rapper Rick Ross and his crew hitting up the Grammys.

"Entertainment Tonight" host, Rocsi Diaz, rocked a white pants suit to the prestige event.

42 year-old Jennifer Lopez might be one of the reasons the Grammys instated a new dress code in the first place (remember that plunging green Versace gown from 2000?!). But she's still looking sexy as ever for tonight's red carpet with her boo Casper Smart by her side.
