LYNWOOD, California -- Actress Lindsay Lohan began serving jail time Tuesday for a probation violation that underlined the starlet's inability to put a 2007 drug case behind her.

Someone showered the actress and the crowd with a blast of confetti outside the Beverly Hills courthouse as she walked in to surrender with dozens of cameras following her.

Two weeks after sobbing at her sentencing, Lohan was more composed but nervous Tuesday, fidgeting with her hair in court as she waited to begin serving her time for violating probation. The judge ordered the cameras off for the moment a bailiff handcuffed the 24-year-old and whisked her into a lockup cell.

Her estranged father, Michael, shouted in court, "We love you Lindsay!"

Los Angeles Superior Court Judge Marsha Revel sentenced the "Mean Girls" star to 90 days in 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.

Sheriff's officials said Lohan will end up serving only about two weeks behind bars because of jail overcrowding and anticipated credits for good behavior. (AP)
