NEW YORK — It was celebs galore as A-listers — from Kate Bosworth to Kirsten Dunst and even some New York Rangers and Tom Brady — climbed the Met's steep red-carpet steps Monday night for its annual Costume Institute gala. The star-studded crowd filed into the congested receiving line, greeted by Mayor Michael Bloomberg and co-chairs Anna Wintour, Nicolas Ghesquière and Cate Blanchett. The hair was coiffed, the makeup heavy and the glamour quotient high — even Kate Moss, though in Topshop, glitzed it up with jewels borrowed from Sir Philip Green's wife, Tina. "I can't wait to see what everybody's wearing," gushed Cameron Diaz. "Isn't that the point?"
