Hilary Is One of Britney's Many Fans in NYC

Britney Spears showed off a few new costumes last night while performing at MSG in NYC. She did her thing onstage after a few days of sightseeing in the city, touring Central Park with her boys after a night at the theater Sunday. Brit also made the rounds yesterday afternoon giving away tickets to her show, though Hilary Duff bought one of her own.
