Hilary Swank (in Marc Jacobs) showed her support for Fergie (in Calvin Klein) last night, who was honored with the Piaget Award of Inspiration at the amfAR Inspiration Gala, held at the New York Public Library. The honor, which recognizes her contributions to the fight against AIDS, was just one part of the mega-evening, which also included a performance by the Philadelphia Eagles cheerleaders, a live auction, and a men's fashion show featuring 79 different looks inspired by the Olympics (think star-spangled Speedos). See more stars at last night's hottest events in the gallery.
