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.

Hilton's publicist, Elliot Mintz, declined 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 is well behaved 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."

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, he 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.
