What brought Gwyneth Paltrow and Bill Clinton to the same London location? A charitable evening, of course! Paltrow was on hand to help Clinton host A Night Out With the Millennium Network, presented by The Clinton Foundation and The Reuben Foundation. Fellow co-hosts included will.i.am of The Black Eyed Peas, and the former president's daughter, Chelsea Clinton. See more stars at last night's hottest events in the gallery.
