The excitement at last night's amfAR Inspiration Gala continued inside Milk Studios after stars like Sarah Jessica Parker, in Chanel, and a Prabal Gurung-clad Kate Hudson moved inside off the red carpet. The ceremony commenced with host Chelsea Handler presiding over the microphone. Katy Perry, in a floral gown, performed at the event honoring uber-agent Kevin Huvane for his work to fund AIDS research. Katy was moved enough to auction off one of her guitars during the charity auction portion of the evening, and Chelsea encouraged would-be bidders to think big, commenting, "Whatever you're thinking, double it!" There was plenty of mingling taking place over dinner — Katy made the rounds saying hi to Kate, Octavia Spencer, Lance Bass, and Kristin Davis. Katy closed the event with a rendition of her song "Fireworks."
