Pink, 2010
Former gymnast
Pink put her skills into action for a gravity-defying performance of "Glitter in the Air." Wearing a barely-there jumpsuit from master costumer Bob Mackie, she rotated over the audience suspended from aerial silks. "I was like, 'Well, why can't I do it and sing?'" she said of the feat. "Everyone's pretty much done everything else there is to do." Although the singer did not go home with a Grammy that night, she did receive a standing ovation from her awestruck peers.
