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

Jennifer Lopez channeled her inner goddess (with a little help from design house Marchesa) for her appearance at the annual Costume Institute gala at Manhattan's Metropolitan Museum of Art. For reporters who clamored to find out what each A-lister was wearing, the job was made easier by those—including Jennifer Garner, Kerry Washington and Jessica Simpson—who arrived on the arm of the very designer responsible for creating their couture. “What are you wearing?” was among the many questions posed, but with Cameron Diaz, Lindsay Lohan and Mischa Barton all in the Big Apple for the fashion fete, one thing was certain—it must have been a very quiet night in Hollywood.
