Even though she’s no Victoria’s Secret Angel, Fergie got in the spirit of the lingerie fashion show when she stepped out on the stage at The Armory in a emerald green halter top that showed off her underwear. She also donned a black leather and fishnets and made sure that during her performances with the Black Eyed Peas, she showed off plenty of leg while models made their way past.

While the models showed off showgirl-style, over-the-top designs in their skimpy lingerie and giant wings, host Heidi Klum took an unexpected walk down the catwalk in a tailor-made design that showed off her post-baby figure.

Many of the models were seen, veritably dripping in jewelry, with Marissa Miller encasing her pert puppies in a $3 million, diamond-covered bra. Who needs a wonder bra with special lifting powers, with jewels like that?
