LOS ANGELES - A judge has told Lindsay Lohan that if she accepts a plea deal on charges of stealing a necklace, she will go to jail.

Los Angeles Superior Court Judge Keith Schwartz told the "Mean Girls" actress that he would sentence her to jail if she pleaded guilty or no contest to a charge filed after a jewelry store reported at $2,500 necklace missing.

The judge said if Lohan doesn't accept a plea deal, the case will go to a preliminary hearing when prosecutors will lay out evidence against the actress.

The 24-year-old said she understood Schwartz's comments. She is due back in court on March 10, when the case will either be resolved or set for another hearing.

Details of the plea deal offered by prosecutors haven't been revealed.
