Lindsay Lohan has been ordered to appear in court on Friday.

There are reports the actress has violated the terms of an alcohol education program imposed in 2007, for driving under the influence of drugs and alcohol.

The 23 year old Mean Girls star risks being sent to jail if she’s found to have broken her probation or other orders imposed as part of her sentence.

It’s also being reported that a Superior Court Judge has told Lohan to attend Friday’s normally routine hearing in person.

Celebrity web site TMZ.com said officials running the alcohol education program expressed concern about Lohan to the court.

In August 2007, the actress and singer was ordered to complete an 18-month alcohol education program.

She was also ordered to serve 24 hours in jail and perform 10 days of community service while on 36 months probation for drunk driving reckless driving and driving under the influence of cocaine.
