Robert Pattinson was just one of the many famous faces that attended the annual Stand Up to Cancer telecast held at LA's Shrine Auditorium today. The event aims to raise awareness and money for the fight against cancer as supporters can call in to donate at any point during the commercial-free broadcast. Gwyneth Paltrow popped up in the philanthropy's signature tee while her husband Chris Martin was overseas rehearsing for his performance with Coldplay at the upcoming Paralympic closing ceremonies. Jessica Biel and Justin Timberlake attended together while Modern Family's Sofia Vergara was on hand to take calls. Olympic swimmer Missy Franklin joined the charitable fun as did Seth Rogen and Minka Kelly.
