Has he learned nothing Paris and Nicole? Everyone knows being a celebrity isn't enough to get off driving offences in Los Angeles any more. Normally, a judge will take a lenient view if a defendant admits blame, but this was Kiefer's fourth driving charge and it meant the court was always going to take a harsh line with him.

"Kiefer will do 18 days for the probation violation, surrendering December 21. He will serve an additional 30 days for the current DUI and must complete that sentence by July 1," an official said. Don't be too downhearted though, Jack Bauer, Nicole Richie's four-day sentence actually translated to just 82mins jail time, so by our calculations you'll be back at CTU in just under 16 and a half hours!
