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

Kristen Bell (in Karen Zambos) celebrated her inner geek—and showed off her outer chic—as she joined Maxim magazine to co-host the Assassin's Creed launch party at Hollywood hot spot Opera. While Bell provided her likeness for the new video game, she stayed mum about the details of how she looks in her animated form. "They're keeping it a secret until they release it," the Heroes star said coyly. "I'm a fan of video games. It was a dream come true."
