If she behaves herself and jails remain overcrowded, Lindsay Lohan will only have to spend 12-13 days behind bars for violating her probation from previous drug and alcohol arrests, a spokesman for the Los Angeles County Sheriff's Department said on Tuesday. It's a big break for Lohan, who was given 90 days by a judge and was initially expected to serve about 23 days of that sentence.

Steve Whitmore told reporters that nonviolent female inmates generally serve about 25 percent of their sentence, principally because of overcrowding in the jail system. He indicated to PEOPLE that Lohan would likely be released from Century Regional Detention Facility either August 1 or 2.
