The clock may be ticking down on Kiefer Sutherland’s time as a free man.  The actor has been charged with misdemeanor assault for allegedly head-butting a man in New York City early Tuesday morning. 

No, Sutherland wasn’t acting out a scene as 24’s Jack Bauer when he got into the alleged altercation with fashion designer Jack McCollough at a New York City nightclub.  Instead, cops described the scene in a statement as "Male white 42, speaking to female white when a male white 30 walked in between them to get to the bar. There was a verbal altercation and the suspect head butted the victim, causing injuries to the victim's nose”. 

And how is this for a Hollywood twist? The female involved in the altercation, according to multiple media reports is Brooke Shields!

You might remember that Sutherland is still on probation from a 2007 DUI conviction which lead to a 48 day jail sentence in Los Angeles.  Authorities there are looking into whether this could be considered a parole violation- if so, Jack Bauer may be spending his summer break in jail.
