Lindsay Lohan: Necklace-Jacking Charges Filed

D.A. submits criminal complaint in court hours before trouble-magnet actress is due to turn herself in

Lindsay Lohan is about to find out the hard way that not every store she walks into is her own personal gifting suite.

That's because the Los Angeles County District Attorney's Office just filed a criminal complaint in court formally charging the trouble-magnet actress with one count of felony grand theft for allegedly stealing a $2,500 necklace from a Venice jewelry store. The move comes just a few hours before she's due to turn herself in at an L.A. court.

On the plus side, at least her hair will be looking good for the judge...

Lohan is expected to surrender at 1:30 p.m. PT at Airport Superior Court, where she will be arraigned on the charge. Her lawyer, Shawn Chapman Holley, has previously said the Mean Girls star plans to plead not guilty.

It was rough night for Team Lohan. A source close to the family exclusively tells E! News that mom Dina "is very upset. She's very, very upset. It was a rough night. The whole family is devastatingly upset. It's very sad. I really can't say anymore." Dina is in New York and won't be present in the court today.

Meanwhile, father Michael tells us that he'll be also sitting out today's hearing due to his ongoing ticker trouble: "[Today's hearing] is a book and release. I am dealing with my heart specialists. Can't be there in the future if I am dead."

And, believe us, there will be plenty of court dates in the future.

Lindsay, who's currently on probation from her 2007 misdemeanor DUI case, is accused of pilfering the bauble from Kamofie & Company on Jan. 22.

After the shop's owner had unsuccessfully tried to get back the so-called "one-of-a-kind" necklace, police were prepared to search Lindsay's home. But before they could execute a warrant, one of Lohan's associates turned in the necklace to police, insisting it was a loaner.

If convicted, Lohan could face up to three years in state prison. But to make matters worse, she's got a Feb. 25 hearing set in her ongoing DUI case, and if that judge determines she violated her probation, he could send her back to county jail immediately.
