Watch: Rihanna, Bruno Mars and Justin Bieber Perform at Victoria's Secret Show

The runway was crowded with sexy for the annual Victoria's Secret Fashion Show.

With special performances from Rihanna, Bruno Mars and Justin Bieber, the VS models strutted in their winged glory like it was everybody's business.

RiRi delivered a dual performance of Unapologetic cuts including her no. 1 single "Diamonds" and the appropriate "Phresh Out The Runway." The fellas also showed out as a fedora-rocking Bruno Mars turned on the charm for his live renditions of "Locked Out of Heaven" and "Young Girls" off his sophomore effort Unorthodox Jukebox. Justin Bieber turnt up alongside the leggy models for "Beauty and a Beat" only to serenade them and the crowd with an acoustic version of "As Long As You Love Me."

Check out the performances from the CBS special below.
