Lindsay Lohan has been sentenced to 30 days in jail for violating her probation in past DUI cases. She must report to jail by Nov. 9.

However, TMZ reports that the actress is likely to be released almost immediately due to overcrowding.

In a court hearing on Wednesday, Judge Stephanie Saunter made it clear that Lohan wouldn't receive a reduced sentence unless required by law. But a spokesperson for the L.A. County Sheriff's Department told TMZ that a federal court order requires inmates sentenced to serve less than 90 to be processed and released shortly after.

Saunter also ruled that the actress must serve 12 days of community service and attend four 45-minute psychotherapy before she returns to court on Dec. 14. The 25-year-old actress is then required to attend four more therapy sessions, and serve another 12 days of community service by January 17.The judge also said the women's shelter where Lohan was previously ordered to serve community service refused to take her back. The Los Angeles County morgue, on the other hand, is willing to accept Lohan's volunteer time. As a result, she will complete all of her required hours there.

If she fails to complete the service and therapy in the allotted time-frame, Lohan faces an additional 270-day jail sentence. Sautner said she was "putting the keys to the jail in the defendant's hands."This will be Lohan's fifth jail sentence since being arrested twice for drunken driving in 2007.
