Lindsay Lohan may be facing a cocaine charge to go along with her alleged California DUI.

Someone apparently leaked an alleged report claiming the troubled actress had cocaine in her system and a blood-alcohol level nearly double the legal limit after the accident.

But the Los Angeles County District Attorney's office is still awaiting toxicology results and no charges have been filed against the 20-year-old Mean Girls star.

On Memorial Day weekend, she allegedly plowed her Mercedes over a curb and into some trees. Police said they discovered a "usable amount" of a substance believed to be cocaine on the scene of the crash. Two days later, Lohan reportedly went to Promises Malibu to sober up.

Lindsay reportedly spent the first stage of her treatment detoxing from alcohol and narcotics, including the painkiller OxyContin, and then would receive intense counseling to avoid using again. Lindsay was expected to check out of rehab earlier this week, but Lindsay may be extending her stay. She cancelled her much-hyped 21st birthday celebration originally scheduled to be a multiday blowout in Las Vegas next week. We hope she gets better.
