Pictures of Leighton Meester, Ed Westwick and Blake Lively Filming in Paris

Blake Lively and Leighton Meester waved to fans from a balcony in Paris while filming Gossip Girl today. They started working on season four in the French capital over the weekend, showing off a variety of the fun outfits we've come to expect from the series. The wardrobe changes kept coming this afternoon, with Blake trading a striped sweater for short shorts. Leighton, meanwhile, went from hot pink to sequins. Ed Westwick was also back in front of the camera with his new onscreen love interest Clemence Poesy. Blake and Leighton took last night off from the set, but they kept design on their minds at the Chanel Haute Couture show.
