Right after [article id="1643079"]Lindsay Lohan was sentenced to 90 days in jail[/article] for violating probation, a Los Angeles County Sheriff spokesman said she likely will only serve a fraction of the time.

Steve Whitmore talked to reporters outside of the court Tuesday (July 6) and said that, because of overcrowding, women sent to jail for nonviolent crimes generally only serve 25 percent or less of their sentence.

The exact time will depend on the wording of the judge's order and the level of overcrowding, reports the Los Angeles Times.

"A person [of] such notoriety will be kept away from the general population," Whitmore added.

Lohan, 24, also was sentenced to 90 days of inpatient rehab. The actress was tearful earlier in court before Judge Marsha N. Revel's sentencing.

"I wasn't trying to get special treatment," Lohan said in court. "I have to provide for myself. I have to work. Having said that, I did everything to balance my jobs and showing up. I'm not taking this as a joke. It's my life. It's my career. ... I take responsibility for my actions. I've tried to do the best I can. It's been such a long haul. I don't want you to think that I don't respect you."

Her plea wasn't enough. Lohan had [article id="1643052"]failed to attend alcohol-education classes[/article], and the judge also cited several instances from over the past few years, saying the actress lied about drinking and taking drugs.

"It's like someone who cheats but doesn't think it's cheating if they don't get caught," Revel said in court.

Lohan will serve her time in Century Regional Detention Facility in Lynwood. She is scheduled to begin her sentence July 20.
