Music's stylishly daring ladies looked to the future for inspiration for Sunday night's out-of-this-world fashion. Fergie channeled a space-age superhero in a skintight metal bodysuit for the Black Eyed Peas' performance. For the last of her three costume changes, Lady Gaga wore a spectacular silver lightning bolt-inspired outfit. And Pink wowed the audience with her performance of "Glitter in the Air," in which she dangled from the ceiling wearing a nude bodysuit decorated with strategically placed piping and glitter.
