Lindsay Lohan is not getting any VIP treatment in prison -- so says her mother, Dina.
Dina -- who visited Lindsay with younger daughter Ali and Lindsay's ex Samanthan Ronson on Thursday -- slammed reports that the 24-year-old actress is enjoying any perks behind bars.
"She doesn't have cell phone privileges, that's absurd," Dina, 47, told Radaronline. "She doesn't even have a pillow to sleep on."
The mom added that she isn't allowed physical contact with her famous daughter during their visits.
"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."
Still, she stressed, "I have to say that the people inside have been pretty cool to her...the guards and the inmates."
The Mean Girls actress -- convicted of violating her probation stemming from a 2007 DUI -- has been behind bars since July 20. Her release date remains undetermined.
Whenever she leaves Lynwood, the star must report immediately to an inpatient rehab facility within the state. On Thursday, Jane Robison, a spokesperson for the L.A. County District Attorney's office, told UsMagazine.com that Lohan must report to her rehab program "sooner" than the 24 hours previously ordered by a judge.
"She does not get to pick the facility," Robison added. "It will be chosen by the judge in consultation with our prosecutor, [Lohan's' defense attorney and the probation department."
