L.A. sheriff's spokesman Steve Whitmore says Lindsay Lohan "has been extremely cooperative" as she begins her three-month sentence for violating probation in a DUI case.
She was booked at Century Regional Detention Facility in Lynwood, Calif., around 10:11 a.m. Tuesday, he told reporters.
"Everything is going smoothly," he said.
She is currently undergoing a routine medical/psychological evaluation before being taken to her 12-feet-by-8-feet cell.
Said Whitmore, "She will be kept away from general population."
Though the actress, 24, received a 90-day jail sentence, her slammer time will likely be reduced due to overcrowding. Whitmore said a "projected release date" could be announced sometime today.
After Lohan surrendered, her attorney Shawn Chapman Holley told reporters that the actress "is asking for your prayers and support. She has stepped up and accepted responsibility."
Holley described Lohan as "a talented young woman and I appreciate that she has accepted responsibility here. She is scared -- as anyone would be -- but is as resolute as anyone could be and she is doing it."
