Kiefer had a little too much fun at the Fox Fall party last night. TMZ reports he was pulled over and arrested for suspicion of a DUI in West Hollywood early this morning and apparently his blood alcohol level was twice the legal limit. He was booked and has been released on $25,000 bail. This is Kiefer's second DUI so if he's convicted he'll be required to go to jail for at least five days. He's scheduled to appear in court October 16.
