Lindsay Lohan is going to jail...again! The starlet, 24, completed just 13 days of her 90-day jail sentence in July, followed by three weeks spent in inpatient rehab. Since being released, Lohan failed two drug tests. And after a probation hearing on Sept. 24, she was taken immediately into custody and denied bail, though another judge overturned that ruling later that day. Will LiLo ever learn her lesson?
