Parties! The style, stars and scoop from Hollywood's hottest events

Christian Slater, Zooey Deschanel and Jaime King co-hosted the Hollywood party that introduced Volkswagen's newest clean car, called the Tiguan, which is designed to release fewer pollutants. Stars like Paris Hilton and Nicole Richie (at left), Ashlee Simpson, JC Chasez, Dita Von Teese and Diane Farr were greeted with the signature Tiguan cocktail, made with Skyy vodka, triple sec, and white-cranberry and orange juices. Guests were also treated to a hot performance by Ludacris.
