LYNWOOD, Calif. (AP) — Lindsay Lohan has arrived at a Los Angeles County women's jail to begin serving a 90-day sentence for a probation violation that is likely to be whittled down to a few weeks.

Her arrival in an unmarked Sheriff's Department car on Tuesday morning at the Century Regional Detention Facility in the industrial suburb of Lynwood, Calif., came about an hour after she surrendered and was handcuffed across town in a Beverly Hills courtroom.

A judge determined two weeks ago that the "Mean Girls" star violated her probation by missing seven alcohol education classes since December.

Sheriff's officials have said Lohan would be placed in an isolation cell at the jail, where she will spend most of her time and take her meals.
