Soon after tweeting her "eeeks" about going to jail, Lindsay Lohan surrendered herself to authorities Tuesday morning to begin serving a 90-day sentence.

Lohan appeared in court with attorney Shawn Chapman Holley. While it was previously reported that Robert Shapiro, a member of O.J. Simpson's defense team, had replaced Holley as Lohan's lawyer, Holley told Judge Marsha Revel that Shapiro had only served as a consultant and that she was still representing Lohan.

Revel denied Lohan the options of home arrest, electronic monitoring, work release or work furlough, which means the troubled starlet will have to serve her time behind bars. She also required Lohan to enter an in-patient rehab facility within 24 hours of her release.

All cameras were ordered off before Lohan was cuffed and taken into custody. Lohan will serve 13 to 15 days, according to Sheriff's Department spokesman Steve Whitmore. Among the reasons: prison overcrowding. She can also get time off for good behavior, he added. "As an incentive for an inmate to behave, they offer them two days off for every six days served," Whitmore told

Lohan tried to keep her sense of humor the night before the start of her jail sentence tweeting: "The only 'bookings' that i'm familiar with are Disney Films, never thought that i'd be 'booking' into Jail... eeeks."

Lindsay Lohan sentenced to 90 days in jail for probation violation

Lohan was found in violation of her probation after missing seven Alcoholics Anonymous classes during a 27-week period. In July, Revel ordered the actress to serve 90 days in jail, followed by 90 days in an in-patient substance abuse program.

In May, Lohan was issued an alcohol-monitoring bracelet after missing a court hearing. The actress was in Cannes at the time promoting the film Inferno, in which she'll play porn actress Linda Lovelace. She has been on probation since August 2007 after pleading guilty to drug charges and no contest to three driving-related charges.

The 24-year-old actress, who previously served 84 minutes in jail in 2007, was to serve her time in the Century Regional Facility, an all-female jail, in Lynwood, Calif. Other celebrities have also served time in Lynwood, just south of downtown Los Angeles, including Michelle Rodriguez, Daryl Hannah, Nicole Richie and Khloe Kardashian.

Standard procedure for any inmate upon arrival includes being checked by two doctors, including a psychiatrist, who will go through Lohan's list of prescriptions and determine what she will be able to take while incarcerated.

In general, inmates are housed in an 8-by-12-foot cell, outfitted with a cot, Sgt. Richard Peña, a spokesman for the Los Angeles County Sheriff's Department, told As a high-profile inmate, Lohan will likely get her own 12-by-12-foot cell, according to ABC News. Inmates are in their cells about 20 hours a day and are able to briefly use an indoor recreation area.

Lohan will get a jumpsuit, which for most inmates is orange. She will be issued a plastic bag that contains soap, deodorant, a tooth brush, toothpaste and other toiletries.

She will receive three meals a day — the same food deputies eat — probably consisting of a hot breakfast and dinner and cold lunch.
