Actress Leighton Meester was all dolled up for her scene with Ed Westwick yesterday in New York City. It must be exhausting, to be a Gossip Girl – their outfits are adorable of course but they are always dressed to the nines. So we understand that Leighton was keeping things casual as she left the set in Brooklyn. She wore a plain but comfy white blouse and took her little dog for a walk once she had finished filming.
