Lauren Conrad Hires Assassin

… to kill Heidi. (Kidding!)

Lauren Conrad attends the official launch of Ubisoft video game “Assassin’s Creed” at Club Opera on Tuesday in Los Angeles. Costar Audrina Patridge was also on hand.

On Sunday, Lauren, 21, dropped by the P.S. ARTS 10th annual ‘Express Yourself’ event at Barker Hanger in Santa Monica, Calif. The event, which also brought out Sex and the City‘s Kristin Davis and Friends‘ Lisa Kudrow, was used to help restore art education in public schools.
