Something happened after the Met's Costume Institute Ball on Monday night. According to the Daily News an incident took place at a SoHo nightspot following the event, and so far the main players have been identified as Kiefer Sutherland, Brooke Shields and designer Jack McCollough. The paper reports that witnesses saw Sutherland get all Jack Bauer on McCollough after he bumped into Shields as she and the actor talked at the bar around 2 a.m. Allegedly Sutherland headbutted the designer and demanded he apologize to the lady. TMZ unsurprisingly reports that Sutherland may have been drunk at the time... and we all know what he's capable of when that happens. (Take 10 seconds to watch him attack a Christmas tree.) The site also notes that a law enforcement source has confirmed that "Brooke was definitely involved" and they are currently reaching out to Sutherland to get his story.
