Pictures of Ed Westwick, Blake Lively, and Leighton Meester on the Set of Gossip Girl in NYC

Leighton Meester was on the set of Gossip Girl in NYC this morning walking arm in arm once again with Hugo Becker, the actor who plays Blair Waldorf's royal love interest. The actress has been busy in the Big Apple since she was off promoting The Roommate last month, but things in her personal life have become complicated — her mother, Constance, was recently accused of making death threats against a woman and her son in LA. Leighton still has been all about work this week, and she had a fresh-from-London Blake Lively on hand to shoot yesterday with Ed Westwick. Ed's equally in-demand with his big- and small-screen projects, as he plans to join Leonardo DiCaprio and Armie Hammer on the set of J. Edgar at some point next month.
