Khloe Kardashian was released from Century Regional Detention Facility in Lynwood County, CA at 1:29 p.m. Friday – just 173 minutes after entering the jail, the L.A. Sheriff’s Department announced on their site.

She turned herself into L.A. Sheriff’s Department custody Friday morning for violating probation following a 2007 DUI arrest and was booked at 8:52 a.m.

Khloe, 23, entered the jail at 10:25 a.m.

Paris Hilton and Nicole Richie were also held at that jail; Richie for just 82 minutes.

Khloe partied with sister Kim and brother Robert Jr. at Matt Leinart’s Celebrity Bowling Night at Lucky Strike Lanes in Hollywood Thursday night.

“She’s not nervous now, but I think she will be tomorrow,” Kim told Jimmy Kimmel on Thursday.

“She definitely has to live up to what she’s done and take responsibility, and she’s willing to do that. I think she just wants it over with,” she added. “Khloe is the tough one.”

She’s “ready and willing” to head to jail, Kim wrote on her blog Tuesday.

Khloe will also have to enroll in an alcohol treatment program — one of the terms of probation she failed to complete — within three weeks of her release.

Kim wrote on her blog: “I urge people to learn from the mistakes of others. Please drink responsibly, and it’s never acceptable to drink and drive!”
