Katie Holmes

Katie Holmes sauntered backstage in Tom Ford's velvet long-sleeved dress with mesh cutouts. The concert—which included performances by the likes of Bruce Springsteen, Paul McCartney, and Kanye West—raised $30 million before anyone even took the stage, according to statements made by Robin Hood Foundation executive director David Saltzman during the event.
