A judge ruled Tuesday that Lindsay Lohan violated the terms of her
probation in a drunken-driving case when she failed to attend alcohol
education classes and sentenced her to 90 days in jail.

Judge Marsha Revel stated several instances over the past few years in which the actress lied about taking drugs and drinking.

"It's like someone who cheats but doesn't think it's cheating if they don't get caught," Revel said.

Before sentencing, a tearful Lohan addressed the court, saying "as far as I knew, I was in compliance with my programs."

"I wasn't trying to get special treatment," the actress said. "I
have to provide for myself. I have to work. Having said that, I did
everything to balance my jobs and showing up. I'm not taking this as a
joke. … I take responsibility for my actions. I've tried to do the
best I can. "

Prosecutors argued that the 23-year-old star of "Mean Girls,"
"Freaky Friday" and "Herbie Fully Loaded" failed to comply with the
weekly attendance directive for her alcohol education classes. An
operator of the class testified that Lohan had nine absences.

Revel was critical of program operator Cheryl Marshall for not
reporting Lohan's absences to the court before the actress had her bail
revoked when the alarm on her alcohol monitoring device was triggered
on June 6 – the same night Lohan attended the MTV Music Awards.

Under questions from the prosecutor, Marshall said Lohan did not
sign in on some days the program claimed she had attended and that her
signature was on a sign-in sheet on a day she did not attend. Marshall
revealed that Lohan never attended group meetings but opted for
one-on-one sessions because of privacy concerns.

Defense attorney Shawn Chapman Holley argued that Lohan was
"absolutely on track to finish the program" and had complied with most
of the court's orders.
