Reports: Lindsay Lohan Had Cocaine in Her System During Crash

"Mean Girl" Lindsay Lohan was fully loaded on more than just booze when she went on a Memorial Day weekend-long bender -- she also had cocaine in her system, according to reports.

Cops said they found traces of blow in Lohan's blood on May 26, the day she crashed her luxury ride in Beverly Hills. Previously, they said they found a personal-use amount of the drug in her car.

Lohan, who turns 21 on Monday, checked herself into rehab several days after she slammed her 2005 Mercedes SL-65 into a Sunset Boulevard curb.

The troubled actress hit rock bottom 48 hours later when she capped off her wild Memorial Day holiday by passing out in a car outside Hollywood's famed Roosevelt Hotel.

Snapshots of the unconscious red-haired temptress made front-page news around the world, and she checked into Promises drug and alcohol rehabilitation center in Malibu a day later.
