Judge says Lindsay Lohan violated her probation in a 2007 drug case(Video)

On Tuesday a  judge  discovered Lindsay Lohan in violation of probation in a 2007 drug case when prosecutors said she was unable to attend court-ordered alcohol education classes.

A sentence was expected later to be released in the day.

The ruling came on a hearing set for the "Mean Girls" star after she failed to appear to  court date in May. She has been ordered to wear an ankle alcohol monitor since then.

Lohan was doing prompotions for a film project during that time at the Cannes Film Festival and insisted her passport was stolen.

Weeks after, the monitor issued an alert following Lohan's attendance at the MTV Movie Awards and after-parties. Prosecutors called it an "alcohol-related" violation.

Prosecutors had expected to reveal reports from the monitor to show the actress also had violated a court order against drinking imposed as part of her probation.

According to Superior Court Judge Marsha Revel, during the ongoing hearing that the device showed Lohan's blood-alcohol content was 0.03.

But, Revel said she would not mull over whether the actress actually consumed alcohol last month after attending the MTV Movie Awards. Lohan has refuted that she was drinking that night.

The judge said she would honor what she told lawyers for both sides in a closed meeting last month and not allow the negative report to be used at the hearing.

Revel said she would only allow whether the actress unable to complete the required number of alcohol education courses on time.

A co-founder of the education program Cheryl Marshall, testified she did not report Lohan violating judge's requirement when the actress missed nine meetings then made up an undisclosed number.

Marshall said she knows that the program received a phone call from the judge in December saying she wanted Lohan to be present in classes each week. However Marshall's reasoning is that she never got a paper copy of the order and did not consider it active.

Marshall's program defended against supplying records and testimony at the hearing, but Revel ruled the information was important.

Lohan's attorney Shawn Chapman Holley said she hadn't planned to fight against the alcohol monitor report because the judge had said it would only affect bail for the actress. Revel doubled Lohan's bail to $200,000 after learning of the alert or violation last month.

Lohan arrived about 10 minutes early for the hearing at the Beverly Hills courthouse.Together with her was her father Michael and younger sister.

Revel had set the hearing when Lohan missed a court date in May. She has been ordered to wear an ankle alcohol monitor since then.

The hearing immediately hit a hurdle as Chapman Holley and prosecutor Danette Meyers argued on what evidence could be introduced.

Lohan spent 84 minutes in jail in 2007 after she pleaded guilty to two misdemeanor counts of being under the influence of cocaine and no contest to two counts of driving with a blood-alcohol level above 0.08 percent and one count of reckless driving.

The petition came after a pair of high-profile arrests earlier that year. Lohan was sentenced to three years of probation but had to ask for a yearlong extension in October when she has failed to accomplish her alcohol-education courses on time.

UPDATES: Sobbing Lindsay Lohan was sentenced on Tuesday to 90 days in jail and requested  to extend another three months in rehab for missing her weekly alcohol education classes in violation of her probation.

"I did everything I was told to do, I thought I was being compliant," Lohan cried,  she told the judge before the sentencing, while her father Michael Lohan wept in the audience. "I'm not taking this as a joke, it's my life and career. I don't want you to think I don't respect you and your terms."
