Hangin' With Kate Moss

Because the room they were in apparently couldn't contain the fun, Kate Moss and boyfriend Pete Doherty decided to take the party outside ... by hanging out of a nearby window. Safe, right?

The cuckoo couple was chilling backstage at the Hackney Empire in London, when Pete decided to play a song on the guitar for a throng of chanting fans down below. Kate joined him on cigarette.
