Los Angeles: 'Mean Girls' star Lindsay Lohan has been released on bail after she was ordered jail for 120 days for violating her probation by allegedly stealing a necklace.

Los Angeles County Superior Court Judge Stephanie Sautner also reduced the charge from a felony grand theft to a misdemeanor.

The court ruled on Friday that Lohan violated her 2007 drunk-driving probation by wearing a gold chain out of a Venice jewelry store Kamofie & Co in January and failing to return it until the police got involved, reported a newspaper.

Besides 120 days in jail, Sautner gave her 480 hours of community service. The 24-year-old actress was led out of the Airport Courthouse after the testimony.

Defence attorney Shawn Chapman Holley immediately sought to post the USD 75,000 bail and filed an appeal of Sautner's decision.

The actress will remain free until her June 3 trial but is required to begin her community service by working 120 hours at the Los Angeles County morgue and 360 hours at the Downtown Women's Shelter on skid row, the judge ruled.

Sautner said the assignments would give Lohan a real-life look at "how truly needy women and women who have fallen on real hard times have to live."

It was the fourth time Lohan was sentenced to jail - she spent a few hours twice and 14 days on a 90-day sentence last summer.
