BEVERLY HILLS, Calif. (AP) -- Los Angeles sheriff's officials say Lindsay Lohan will likely spend about two weeks of her three-month sentence in jail.
Department spokesman Steve Whitmore says Lohan is likely to be released on Aug. 1 or 2. The projected release date reflects all the credits Lohan is likely to receive. The department has said the actress was likely to serve a quarter of her sentence or less, in part because of jail overcrowding.
The actress surrendered at a Beverly Hills courthouse Tuesday morning.
The "Mean Girls" star was sentenced to serve 90 days in jail earlier this month after a judge determined she violated her probation.
Lohan arrived about 10 minutes late and was accompanied by attorney Shawn Chapman Holley and her mother, Dina. The 24-year-old has been free on bail since missing a court hearing in May for a 2007 drug and alcohol case. She has been on probation since August 2007 after pleading guilty to misdemeanor drug charges and no contest to three driving charges.
On July 6, Los Angeles Superior Court Judge Marsha Revel sentenced the "Mean Girls" star to jail, three months in rehab and increased scrutiny by probation officials after determining the actress violated her probation by missing seven alcohol education classes since December.
Lohan, 24, burst into tears after hearing the sentence, which came after she tearfully apologized to the judge for not strictly following the terms of her probation.
Dozens of cameras and reporters converged on the courthouse Tuesday morning to chronicle Lohan's arrival and her return to custody.
On Friday celebrity attorney Robert Shapiro signed on to the case after Lohan moved into a sober living facility that he founded. By Monday night, the Los Angeles Times and celebrity website TMZ.com, citing anonymous sources, reported that Shapiro had resigned from the case.
Shapiro met with Revel in a closed meeting late Monday afternoon. The prosecutor handling the case, Danette Meyers, was not present and court officials said there had been no change in requirements for Lohan's surrender.

In an e-mail to The Associated Press sent Monday evening after the meeting, Shapiro said his only comments would be made in open court.
Lohan, a prolific user of the microblogging site Twitter, posted a message roughly 12 hours before her court appearance referencing her looming incarceration.
"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' projects in limbo, including her planned portrayal of porn star Linda Lovelace in a biopic.

Once considered an up-and-coming star, Lohan has in recent years been better known as a tabloid staple and for the criminal case she has struggled to put behind her.
Her probation had to be extended for a year to give Lohan more time to complete her alcohol education courses and Revel ordered weekly attendance in December.
But the actress didn't complete the sessions as ordered and missed a court date in May, setting the stage for her return to jail. She is expected to serve her time in isolation at a women's jail in the industrial suburb of Lynwood.

The facility has hosted several female celebrities, including Paris Hilton, Nicole Richie, Michelle Rodriguez, Khloe Kardashian and very briefly, Lohan.
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.
She will be forced to wear a jail-issued jumpsuit and be given a set of simple toiletries that all inmates receive: toothbrush, toothpaste, soap, comb, deodorant, shampoo and shaving implements. Hilton received one for her own secluded 23-day stay in 2007 for reckless driving charges.
