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

Hilton was ordered earlier this month to report to jail by June 5 for violating the terms of her probation in an alcohol-related reckless driving case.

Hilton initially called the sentence unfair, and lawyers representing her filed a notice to appeal the sentence.

She then switched attorneys and is now represented by drunken driving specialist Richard Hutton. Hutton did not immediately return several calls for comment Thursday.

The hotel heiress 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.
