Wearing dark denim jeans, a grey top, black corset belt and black jacket, the 24-year-old actress had arrived at a Beverly Hills court about 10 minutes late.
After a short hearing, she was handcuffed behind her back to serve her time for a probation violation.
Lohan was accompanied to court by her mother Dina and younger sister Ali, who wiped away tears after her sister was taken away.
Her estranged father Michael Lohan yelled “We love you, Lindsay” as his daughter was led away. She was then taken across town to the Century Regional Detention Facility in the industrial suburb of Lynwood.
While Los Angeles Superior Court Judge Marsha Revel did not address Lohan's lateness yesterday directly, she did order her to report to probation officials within a day of her release from jail. The judge had previously ordered Lohan to report within two days.
Judge Revel has ordered officials not to allow Lohan to serve any of her sentence on house arrest or work release.
Two weeks ago, the judge determined that the Mean Girls star violated her probation by missing seven alcohol education
classes since December.
She had been on probation since August 2007 after pleading guilty to drug charges and no contest to three driving charges.
Lohan, a prolific user of Twitter, posted a message roughly 12 hours before her court appearance referring to her looming imprisonment.
“The only ‘bookings' that I'm familiar with are Disney Films, never thought that I'd be ‘booking' into jail ... eeeks,” Lohan posted.
The jail and rehab stints have left some of the actress's projects in limbo, including her planned portrayal of porn star Linda Lovelace in a biopic.
