Lohan served 13 days of her 90-day sentence. She had been in jail since July 20 after violating her probation in two DUI cases.
According to celebrity news website RadarOnline.com, Lohan will not be going to Morningside Recovery, but to another rehabilitation facility in the West Los Angeles area due to Judge Marsha Revel's suspicion that the actress might have access to drugs from the public. TMZ.com reported that Lohan will check into a rehab program at Ronald Reagan UCLA Medical Center.
It was also speculated that 24-year-old Lohan would have 24 hours of freedom before checking into rehab, but pulished reports said she would immediately be transported to a facility.
Lohan was sentenced to serve time after violating her probation. She was supposed to make weekly appearances at an alcohol education program.
Officials had said Lohan would likely serve only a fraction of her sentence due to jail overcrowding and because she's a nonviolent offender serving time on a misdemeanor.
Sheriff's officials previously said they would increase security when Lohan would be released. A horde of paparazzi swarmed the Lynwood jail all day Sunday to Monday morning to capture images of Lohan as she left.
