Prosecutors said Tuesday they plan to charge Lindsay Lohan with felony grand theft of a $2,500 necklace reported stolen from a jewelry store last month.

District Attorney's spokeswoman Jane Robison said the charge will be filed Wednesday. She is due in court for an arraignment on Wednesday afternoon.

The charge brings the troubled star another step closer to jail. Lohan, 24, remains on probation for a 2007 drunken driving case and a judge had threatened to throw her in jail if she ran into trouble again.

Los Angeles police said Feb. 2 that Lohan was under investigation for taking a necklace from a Venice store later identified as Kamofie and Co. Detectives obtained a search warrant to try to retrieve the item from Lohan's home, but it was turned into a police station before any search was made.

A phone message to Lohan's attorney, Shawn Chapman Holley, was not immediately returned. Holley has previously denied Lohan stole the necklace and vowed to fight any charges in court.

The new case represents the most serious charge the "Mean Girls" star has ever faced. Arrested twice in 2007, Lohan was charged with drunken driving and drug possession, but both were misdemeanors.
