LOS ANGELES (AP) -- Khloe Kardashian's next dose of reality will involve the county jail.

The youngest daughter of famed defense attorney Robert Kardashian admitted violating her probation stemming from a 2007 drunken driving arrest during a July 3 court hearing, according to court records.

A Los Angeles Superior Court judge ordered Kardashian, who's featured on E! Entertainment Television's "Keeping Up With the Kardashians," to surrender to authorities on Friday and serve up to 30 days in jail.

Kardashian 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. She will also remain on probation.

"Khloe is ready and willing to serve out her sentence, no matter how long and where, and have this resolved," her publicist, Jeff Raymond, told The Associated Press.

It's unclear how long Kardashian, 23, will remain in jail. Other, more famous celebrities including Paris Hilton and Nicole Richie have served shortened sentences because of jail overcrowding.

Her drunken driving arrest was featured in an episode of the E! series.
