Charlotte's siblings showed up to do DJ sets and support their sister, with Mark and Samantha both hitting the decks and hanging out with friends like Mischa Barton at the party. Other famous guests included Sophia Bush, Olivia Thirlby, Hilary Duff, Zoe Kravitz, Sean Lennon and Mischa's The Beautiful Life costar Ashley Madekwe. What a star studded bash!
