In addition to Theron, 38, and Penn, 53, the party was attended by Jamie Foxx, Johnny Knoxville, Adrian Grenier and Alicia Keys. Destiny's Child's Michelle Williams and Kelly Rowland, and jewelry designer Lorraine Schwartz were also on hand. At one point in the evening, the "Young Adult" actress was photographed with her head resting on her beau's shoulder.
