At a hearing in Beverly Hills today, a judge added an additional year to Lindsay Lohan’s existing three-year probation sentence, according to People. Earlier today, Lohan was ordered to appear in court for a progress report in her two DUI cases from 2007. Once there, the actress’ attorney, Shawn Chapman Holley told Judge Revel that there had been a miscommunication: Lohan hadn’t informed the instructors of her alcohol education class that she would return to the course after she left the country for work. Revel told Lohan, “I ordered you into court today because I wanted to speak to you directly. I don’t want to get any more notices again [that you might be in violation of probation], no warrants … where you’re thumbing your nose at the court.” He then ordered the actress to get prior court approval before leaving Los Angeles for work and warned her that any failure to comply with the terms of her probation could lead to jail time. “I’m rooting for you to successfully complete probation,” he added. Lohan’s only words in court were “yes” when asked if she understood all the proceedings. Her next progress review hearing is Dec. 15.
