TMZ seems to think so. The gossip site has learned that Lindsay Lohan could be in serious trouble with the law for not following the terms of her court-mandated alcohol education classes. It’s a violation of her probation, and there’s good reason to think she’ll end up doing hard time as a result.

Judge Marsha Revel ruled that LiLo must attend alcohol classes at least once every seven days, unless Lohan received treatment through inpatient rehab. The judge ruled that if Lindsay violated this agreement, Lohan would be going to jail. Well…she’s violated it.

Lindsay Lohan will face the music on May 20, a progress hearing where it will be revealed that Lohan frequently waited up to 21 days to attend her court-mandated courses. If the judge holds firms to her former ruling, Miss Lohan will find herself behind bars before the day is out.
