LATEST: Actor Tom Sizemore's 16-month prison sentence has been cut in half thanks to the 213 days he has already spent behind bars and in court-imposed rehab. The Black Hawk Down star was sentenced to serve jailtime for violating his probation in a 2004 crystal methamphetamine possession case. But he's already received the good news that his original sentence has been cut in half - to eight months. A Los Angeles County Superior Court judge credited Sizemore with 213 days for time already spent in jail and in two live-in drug treatment programmes on Tuesday (26Jun07). Sizemore will serve his sentence at Donovan Correctional Facility near San Diego, California. The 45-year-old star previously admitted violating his probation when police found two bags of crystal methamphetamine and pipes in his possession during an arrest last month (May07) in Bakersfield, California. In a court appearance last week (ends22Jun07), he tearfully begged the judge to give him another chance to overcome his drug problems.
