Kiefer Sutherland on Wednesday was formally sentenced to 48 days in jail for his second drunken-driving arrest in three years, and immediately reported to Glendale city jail. Though the 24 star could have waited until Feb. 12 to start his stint (which needs to be completed by March 30), "Kiefer made the decision to surrender to custody immediately," his attorney tells the Associated Press.

The Glendale jail is a minimum-security facility with 48 cells, each measuring 10 feet by 8 feet and equipped with a toilet, sink, water fountain and two beds, though Sutherland won't be sharing his cell with anyone.

Sutherland pleaded no contest in October to driving with a blood-alcohol level above the legal limit of .08.
