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 for the private party, hosted by Bionic Yarn, G Star and Hennessey. Williams' pals were all out to celebrate the singer's Oscar nomination for his hit "Happy" and Foxx congratulated him on the mic, the insider added.

At one point in the evening, the Young Adult actress was photographed with her head resting on her beau's shoulder. They also danced with the crowd to Williams' new album GIRL.
