Lindsay Lohan was twice sprung early in her previous stays at a Lynwood, Calif., jail, serving only a fraction of her sentences.
Not this time.
"Ms. Lohan cannot be released early because this isn't a jail sentence," L.A. Sheriff's spokesman Steve Whitmore says. "She's being held by court order until her hearing on Oct. 22. She will be held in the same conditions as her last stay, in a keep-away unit."
Barring any unforeseen circumstances, Lohan will remain at the all-female-inmate facility for the next 29 days.
"She's now being processed through, she's going to go through the same physical and mental evaluation," says Whitmore, adding that she'll be segregated from the general population "for the safety and security of the entire jail system."
Whitmore adds that Lohan is "very cooperative, very demure, very quiet. Once again she's doing everything that is asked of her. Last time she did very well and so far, so good this time.''
Lohan, 24, once again donned an orange jumpsuit and is expected to be held by herself in an 8-by-12 foot cell, where she could spend approximately 23 hours a day.
Those hours in confinement are shortened, however, on days when she's visited by her lawyer and loved ones.
The actress was ordered into custody Friday and held without bail after she failed a recent drug test in her DUI probation case.
