Mean Girls star Lindsay Lohan, who was previously sentenced to 120 days in jail and 480 hours of community service for stealing a $2,500 jewelry from a swanky jeweler, has been put under house arrest.

On May 11, Lohan was originally sentenced to 120 days in jail and 480 hours of community service after Lohan’s lawyer pleaded no contest on her client's behalf to her charge of leaving a jewelry shop in Venice, California, with a $2,500 gold and diamond necklace without paying for it. Lohan was to begin the sentence on June 17.

However, Lohan showed up in court on Thursday to begin her 120-days jail sentence and was told to undergo house arrest instead as it was determined that, as a non-violent offender, the actress was eligible for home confinement.

After being deemed eligible for home confinement, Lohan was fitted with an electronic monitoring ankle bracelet and released to her home within an hour, Los Angeles Sheriff's department spokesman Steve Whitmore said.

Ms. Lohan will be under the supervision of the sheriff's department and her release date is expected to be around June 29, Whitmore said. She will serve about 35 days on home detention.

The duration, however, could be reduced further because of the jail overcrowding.

Because of budget constraints and because we’re under a federal consent decree that requires us to curb our overcrowding situation, nonviolent offenders, lesser crimes, get 20% of their sentence, Whitmore explained.

Lohan, who has been cast alongside actors Al Pacino and John Travolta in a film based on New York crime boss John Gotti, has been in and out of court - and sometimes jail - since 2007 when she was arrested twice for drunken driving.
