Gibbons said the hearing "apparently has something to do with Ms. Lohan's probation. We don't know exactly what it's about. The court contacted the defense directly, not us." Unidentified sources reportedly told TMZ.com that the warrant was issued after Lohan failed to comply with the terms of her probation, specifically with regard to an alcohol-education program in which she is enrolled. TMZ also reported that police were called to Lohan's girlfriend Samantha Ronson's house after a disturbance involving a broken window was reported on Saturday, but left without apprehending Lohan. The actress reportedly spent Friday evening with friends at the Chateau Marmont in West Hollywood, and then the group made a late-night visit to the house of Jack Nicholson.
In August 2007, Lohan pleaded guilty to two counts of being under the influence of a controlled substance (cocaine), and no contest to two counts of driving with a blood-alcohol level above .08 percent and one count of reckless driving. She served 84 minutes in jail in November 2007 and was placed on three years probation and ordered to complete an 18-month alcohol education program.
