Lohan is set to be arraigned Wednesday for allegedly lying to authorities when she said she wasn't driving last June on the day when her Porsche hit an 18-wheeler on the Pacific Coast Highway. Law enforcement sources tell the website that the judge plans to revoke Lohan's probation for the jewelry theft case, as well as set a hearing to formally rule whether Lohan violated the terms of her probation by breaking the law again.
Even if Lohan is found not guilty on criminal charges, her probation could still be revoked, meaning Lohan could face up to 8 months in jail, not including additional jail time if she's convicted of lying to police.
Lohan is currently on "informal" probation until May 2014 for pleading no contest to stealing a necklace from a Venice jewelry store in January 2011. She completed her supervised probation this past March after finishing her community service and required therapy.
