Paris Hilton won't appeal the 45-day jail term she was sentenced to this month for violating probation, according to court documents filed Thursday.

A lawyer for the 26-year-old socialite notified Los Angeles County Superior Court that she is abandoning her appeal, said court spokeswoman Katherine Roberts.

Hilton was ordered to report to jail by June 5 for violating the terms of her probation in an alcohol-related reckless driving case. She initially called the sentence unfair, and lawyers representing her filed a notice to appeal.

She has since changed legal teams and is now represented by Richard Hutton, a lawyer specializing in defending drunken driving cases. Hutton didn't immediately return calls for comment Thursday, and Hilton's publicist, Elliot Mintz, declined to comment.

Hilton is likely to spend about 23 days in a "special needs housing unit" at the Century Regional Detention Center in suburban Lynwood, said Los Angeles County sheriff's spokesman Steve Whitmore.

The shorter sentence reflects an expectation that she will behave well behind bars.

"All inmates get credit for good behavior," Whitmore said. "The inmate knows that if they behave and follow the rules, that's something to shoot for."

The day and time she might report to jail remains unknown. Though most inmates are processed between 6 a.m. and 10 p.m., there's nothing to prevent them from showing up unannounced at another time, authorities said.

Hilton will be separated from the general inmate population in a unit that contains 12 two-person cells reserved for police officers, public officials, celebrities and other high-profile inmates, Whitmore said. She could have a cellmate.

Like everyone else in the 2,200-inmate facility, Hilton would get at least an hour outside her cell each day to shower, watch television, participate in outdoor recreation or talk on the telephone, he said.
