New York City was filled with scantily clad women last month to film the annual Victoria's Secret fashion show - which finally aired Tuesday night on CBS. Rihanna, Justin Bieber and Bruno Mars performed at the event, which was held at the Lexington Armory.

Rihanna sang "Diamonds" and "Fresh of the Runway" from her new album "Unapologetic" and held hands with sexy model Doutzen Kroes (above) as they hit the stage. The pop star didn't just sing at the show - she also modeled some pink lace lingerie.

Angel Lily Aldridge tweeted, "Rihanna is soooo stunning!!!!!! Killed it at VS FashionShow."

The models sizzled in a vast aray of outfits, including patriotic, circus, and jungle-themed ensembles.
