So long, slammer.

After 13 days behind bars, Lindsay Lohan was released from the Century Regional Detention Facility in Lynwood, Calif., around 1:35 a.m. Monday.

Lohan, 24, now is in rehab. Though she was originally set to spend three months at high-end residential facility Morningside Recovery in Orange County, Calif., she will report to the UCLA Medical Center, according to TMZ.

After she completes treatment, the actress will be subject to random drug and alcohol testing until Aug. 2011, when her probation term ends. She is still allowed to take certain prescription medications.

Lohan had been behind bars since July 20 for violating probation in her DUI case. (She was originally sentenced to 90 days but was released early due to good behavior and overcrowding.)

Her time in the slammer was fraught with drama.

When she was first taken to her 12-by-8 cell, she was "crying," said Alexis Neiers (of E!'s Pretty Wild), who was in jail at the same time for burglarizing Orlando Bloom's home.

"She was talking to deputies and, you know just trying to — I couldn't really like make it out - but from what I saw the first day, I mean, she was lying in there and just trying to like calm down," she said.

Though some inmates claimed the actress was receiving special treatment, her attorney Shawn Chapman Holley told UsMagazine.com that was not the case and that Lohan had even "made some friends."

Her mother Dina was most outspoken about her daughter's time behind bars.

"She doesn't have cell phone privileges, that's absurd," she said. "She doesn't even have a pillow to sleep on. I talk to her through glass. There's a phone and we put her on speaker but I can't even hug my daughter ... She's treated like a common criminal."
