In the most bizarre news from last night's Met gala, Kiefer Sutherland allegedly head-butted Proenza Schouler designer Jack McCollough so hard he broke his nose at an after-party at SubMercer. McCollough had to go to the hospital, where, according to Guest of a Guest, he remained at around 1 p.m. today. Proenza reps were unable to confirm the report. Guest of a Guest writes, "While guests like Mary-Kate Olsen (who hit up more than one party of course), and Kirsten Dunst looked on, the actor apparently was upset over Brooke Shields." Your guess is as good as ours as to what that means. [Guest of a Guest]
