Perry attended the event with her parents Keith and Mary, as well as her older sister Angela.

A source tells EOnline.com, "Katy is so proud of David. She was screaming out her support and had a really great time. It is a very supportive family."

Perry wasn't the only star in attendance - David Arquette, Mary-Kate Olsen, Paris Hilton and her ex-boyfriend Good Charlotte rocker Benji Madden were also in the crowd.
