A slew of stars, including Katherine Heigl, Eva Mendes, and Demi Moore and Ashton Kutcher, put on their Saturday-night best and journeyed up to a palatial Mandeville Canyon mansion this weekend for the Seventh Annual Chrysalis Butterfly Ball. The evening raised a cool million dollars for the organization, which is dedicated to helping California's homeless men and women find jobs. Rebecca Gayheart played co-host, which explained the noteworthy contingent of man candy, namely her husband, Eric Dane, and his Grey's Anatomy castmates Justin Chambers and T.R. Knight. "I want to thank my presenters, who are also really hot," joked Gayheart. Meanwhile, master of ceremonies Chris Kattan made sure to remind the glossy crowd what the night was really about. "When I say homeless," he explained, "I don't mean I only got two episodes of Gossip Girl this season and I can't pay the rent in Larchmont."
