Thursday, a lawyer for the 26 year-old told the Los Angeles court that they are no longer planning to appeal.
Hilton, who stars in television’s Simple Life, will begin her sentence on June 5 at a detention centre in Lynwood, near Los Angeles.
The starlet was sentenced after being found guilty of violating her probation, and driving her car with a suspended license.
Yesterday, a spokesperson from the Los Angeles Sheriff’s Department revealed that Hilton’s sentence has been shortened to just 23 days. Hilton will also likely receive special treatment while serving her time. The Lynwood centre is home to 2,200 prisoners. Hilton will have only an hour each day to leave her cell, when she can watch television or make phone calls.
