Victoria's Secret fashion show

The Victoria's Secret fashion show was held Thursday night at the 69th Regiment Armory, and, shockingly, Heidi Klum walked the runway only five weeks after giving birth to her fourth child.

USA Today reported that although Klum was hosting the show, she decided to make a surprise walk down the runway as well. Some other surprise runway walkers were the members of Black Eyed Peas, who appeared on a black v-shaped runway.

The show ranged in style from futuristic to playful, with giant feathers, armored wings, and neon colors. The Pink line included sparkly bras, lots of hearts, and trains made of balloons.

Celebrity attendees included Jay-Z, Dr. Dre, Michelle Trachtenberg, and members of the Kings of Leon. The show will air on CBS, Dec. 1.
