Lindsay Lohan was taken into custody on Tuesday to start a 90-day jail term for violating her probation on a 2007 drunk-driving and cocaine-possession charge.
Lohan arrived about 10 minutes late and was accompanied by attorney Shawn Chapman Holley and her mother.
The 24-year-old has been free on bail since missing a court hearing in May for a 2007 drug and alcohol case.
Revel sentenced Lohan two weeks ago after ruling that the "Mean Girls" actress had again failed to complete weekly alcohol education classes imposed in 2007. Lohan must also attend a 90-day residential rehabilitation program on her release from jail.
Lohan, wearing a grey T-shirt, looked tired and tense at the brief court hearing. She did not speak.
Her stay will be longer than the 84 minutes she spent at a suburban Los Angeles jail in 2006 and marks the beginning of a new phase of punishment for drug and alcohol cases filed that year.
Los Angeles Superior Court Judge Marsha Revel sentenced the "Mean Girls" star to jail, three months in rehab and increased scrutiny by probation officials on July 6 after determining the actress violated her probation by missing seven alcohol education classes since December.
