Lindsay Lohan may be turning Winona Ryder faster than we all thought. The Los Angeles Police Department currently considers her a suspect in the theft of $100,0000-worth of watches and sunglasses - and the "Herbie Fully Loaded" star could be facing serious jail time if she is found to have violated her probation.

Lohan's latest legal troubles erupted last week when she and her assistant, Gavin Doyle, were party guests at the Hollywood Hills home of millionaire Sam Magid, who later called cops to report a jewel theft. Lohan, who's been at the house frequently recently, tried to leave the all-night party at around noon the next day, Aug. 20, but the owner realized several expensive watches and some sunglasses were missing before she got the chance. He told everyone to stay and then called cops.

Although Magid recanted his story about his missing goods just days after reporting the theft, sources said cops have continued with their investigation and believe they have independent witnesses who will identify Lohan and Doyle as the thieves.

In 2010, Lohan was suspected of stealing a $35,000 Rolex watch, and in 2008 when she was accused of ripping off an $11,000 mink. Both incidents were eventually deemed misunderstandings and she was not charged.

LAPD detectives contacted lawyers for Lohan yesterday, asking for an interview with the two suspects, but were rejected, According to TMZ. A representative for Lohan declined to comment. Cops told The Post they're meeting with the DA, and the case is still under investigation.

Lohan is still on probation from an earlier theft case involving a necklace swiped from a Venice, Calif., jewelry store a year ago. If she's found guilty this time, she could go to jail for violating her probation.

Lohan is also being investigated for lying to police after a car crash in which she said she was just a passenger in the car. Cops think she was the driver. TMZ says the case will be referred to prosecutors and the L.A. City Attorney for a possible probation violation.

And these aren't Lohan' only legal problems. Santa Monica police detectives have been trying to get in touch with Lohan to ask her questions about a car crash last June, when she slammed into a big rig on the Pacific Coast Highway. Sources say Lindsay's lawyer, Shawn Holley, called the station and complained that cops should not be calling Lindsay directly because she has an attorney.

Lindsay lied to cops when she told them she was a passenger and not the driver. Cops are convinced Lindsay was indeed behind the wheel and are now investigating.

Sources tell us the follow-up questions relate to Lindsay's alleged lying to cops -- which is a crime punishable by one year in jail. We're told the case will be referred to prosecutors. It will also be sent to the Los Angeles City Attorney for a possible probation violation in her necklace conviction.

Lohan also recently completed filming the Elizabeth Taylor biopic "Liz and Dick," during which she tweeted photos of the jewelry (all fake) she wore on set.

"Cleaning MY jewels :) ...... I love feeling like Elizabeth @DameElizabeth @damelindsay."
