Millionaire heiress to the Hilton Hotel chain and convicted traffic felon Paris Hilton will be released from the Century Regional Detention Facility in Lynwood tomorrow.

The socialite, who was briefly released earlier this month on undisclosed medical grounds before being sent back to prison, had served roughly half her 45-day sentence for violating her probation on a drink-driving case.

She is due to give her first official account of life behind bars on Wednesday to Larry King in a one-hour special on US network, CNN.

“I am thrilled that Larry King has asked me to appear on his programme to discuss my experience in jail,” says Paris.

“What I have learned, how I have grown and anything else he wants to talk about.”

Fans hope it will also reveal more on reports that Paris has found religion and wants to build a halfway house for women recently released from prison.
