Gwyneth Paltrow had a dressed-up afternoon in NYC yesterday. She went out to lunch in a tight brown dress from Burberry Prorsum, which she paired with a Victoria Beckham bag. Gwyneth then changed into pants and a white blazer for a dinner out with friends. Gwyneth's in NYC following a stay in LA, where she hung out last week. She's skipped out on the world tour promoting her latest big-screen effort, The Avengers. Her Marvel costars Robert Downey, Jr. and Scarlett Johansson are expected in the Big Apple themselves this weekend — The Avengers will close the Tribeca Film Festival with a red-carpet event on Saturday. Gwyneth and Robert will soon reunite to shoot Iron Man 3 as well. There are rumors Jessica Chastain will join the Iron Man franchise in the next installment, too.
