Not even Jack Bauer could get out of this one.

The actor who plays him, Kiefer Sutherland, pleaded no contest Tuesday to a charge of driving with a blood-alcohol level above the legal limit and will serve 30 days in county jail under terms of a plea agreement.

Attorney Blair Berk entered the plea on behalf of Kiefer Sutherland, who was not present. As part of the arrangement, Sutherland must also enroll in an 18-month alcohol-education class and attend weekly alcohol-therapy sessions.

The charge of driving with a blood-alcohol level of .08 percent or higher stemmed from a traffic stop in Los Angeles last month.

A second misdemeanor charge, driving under the influence, was dropped.

Kiefer Sutherland is on probation for a 2004 drunk driving arrest. Superior Court Judge Stuart M. Rice revoked the actor's probation in that case.

Sutherland, star of Fox's 24, could face six months in jail for violating probation. Sentencing is set for December 21, the same day the show begins its winter break.

And the list of celebrities arrested for DUI - and even serving time behind bars, albeit briefly - continues to swell. Who's next?
