Ooh la la!  We spotted Blake Lively slipping into her trailer wearing a very tiny robe while on the set of Gossip Girl today, which is currently filming in the Hamptons for the promised "beach scandal".  Also on set were Leighton Meester (also relaxing in a robe), Penn (who seems committed to those baggy shorts) and Penny, who is climbing the ladder to become my favorite celebrity dog.
