Leighton and Taylor on Set, September 2, 2010

SPOTTED: Leighton Meester and Taylor Momsen back at it again on the New York set of Gossip Girl. As usual, Tay arrived to work in a barely-there ensemble of tiny shorts, ripped tights, and an Iron Maiden t-shirt. Leighton, on the other hand, looked chic, summery, and fun in edgy grommet shorts and bright orange sunglasses. Better get your fill of hot-weather fashion now, L! Autumn boots and sweaters are right around the corner.
