The Los Angeles jail where Nick Reiner is being held on two charges of first degree murder has a star-studded history with a reputation for harsh conditions.

Page Six can confirm Twin Towers Correctional Facility, which is a mental health jail, once housed A-listers from Paris Hilton to Harvey Weinstein.

Hilton briefly served time at the facility back in 2007 during her 45-day sentence for violating probation on alcohol-related reckless driving charges from 2006, multiple outlets reported at the time.

As for Weinstein, he was transferred from Wende Correctional Facility in New York to the Twin Towers Correctional Facility in July 2021 to face additional charges of sexual harassment.

Michael Jackson’s doctor Conrad Murray — who was convicted of involuntary manslaughter in the King of Pop’s 2009 death and sentenced to four years behind bars — temporarily stayed at the jail before being transferred to other facilities.

Other famous faces who had brief stints at Twin Towers include actor Robert Downey Jr., “Jackass” star Steve-O, convicted murderer Robert Durst, rapper The Game and other stars.

But the jail’s star-studded history doesn’t mean the facility has lux accommodations, as Twin Towers has been accused of harsh conditions.

Beverly Hills Defense Attorney Adam Michael Sacks exclusively told Page Six, “You don’t want to be there, it’s disgusting. Every client I went to visit begged for bail.”

As for the food, Sacks described it as “slop.”

“The food is disgusting,” he added. “It makes cafeteria food look good.”

New York Post elaborated on the harsh conditions inside the facility through inspection reports and court filings.

The Post reported county commissioners have claimed cells have feces on walls, urine on floors and concrete walls covered in graffiti.

Sheriff’s deputies have shut off water to cells — including drinking water — when toilets are intentionally flooded, inspection findings claim.

California Attorney General Rob Bonta filed a lawsuit against the Los Angeles County, Sheriff’s Department and Correctional Health Services regarding the alleged “inhumane” conditions in September.

The lawsuit claims Twin Towers is filled with mold and rust, while rats plague housing units and black worms infest shower stalls.

The Los Angeles Sheriff’s Department told The Post that $309 million went into upgrades — including hiring more staff, fixing infrastructure and other improvements despite the claims.

Twin Towers Correctional Facility did not immediately respond to Page Six’s request for comment.

Rob, 78, and Michele, 70, were found stabbed to death in their Brentwood home in Los Angeles in the afternoon of Dec. 14.

According to the death certificate released on Tuesday, Rob and Michele died within “minutes” from “multiple sharp force injuries” with a “knife, by another.”

Sources initially told The Post that Nick was considered a person of interest in the fatal stabbings.
