Kiefer Sutherland vs. Brooke Shields over 'heroic' headbutt

Keifer_brooke_290 "24" star Kiefer Sutherland headbutted a man at an after party for the Met Costume Institute gala at Submercer on Monday, but he claims it was all to defend Brooke Shields' honor, not from public drunkenness as some have reported.

Not so fast, says the lady in question. Shields denies the story that she was knocked down by Proenza Schouler designer Jack McCullough, which necessitated heroic action from Sutherland. Shields' rep tells TMZ.com, "Jack did nothing inappropriate. It's not clear what caused Kiefer to do what he did."

McCullough reportedly has either a broken nose or lacerations on his nose as a result. Police are investigating the matter.

Sutherland is currently on probation in Los Angeles for a DUI.

Okay, maybe we're crazy, but even if someone goes around shoving other folks, when is a headbutt the next logical action? When you're an extra in "Braveheart"?
