Kristen Bell was the host (and life) of the party at last night's Maxim event at Opera nightclub in LA celebrating the video game Assassin's Creed. Seriously, the new Heroes star was air guitarring and handing out flowers and dancing up a storm with her costars. Whooo, party! That isn't to say she was the only one having fun, The Hills girls definitely know how to have a good time. Cute Zachary Levi from Chuck may be new to the Hollywood party scene, but he already fits right in alongside his costar Joshua Gomez. They'll be having girls fighting over them in clubs in no time.
