Report: Paris Hilton released from jail

US celebrity hotel heiress Paris Hilton has been released from prison in Los Angeles after serving just three days of her 23-day sentence for a probation violation, it was reported today.

Website TMZ had learned that Paris Hilton has not only had her sentence cut short, she was already out of jail.

"Unimpeachable sources tell TMZ the deal was sealed yesterday, and that Hilton made her exit early this morning," said TMZ.

She was originally sentenced to 45 days in jail, but that was reduced to 23. She served a total of three days.

The LA County Sheriff's Department is to hold a news conference later today, the website said.

The 26-year-old Hilton checked into the Century Regional Detention Facility in suburban Los Angeles just after 11.30pm local time on Sunday to serve 23 days for violating probation in an alcohol-related reckless driving case.

Hilton surrendered after a surprise appearance earlier that day at the MTV Movie Awards, where she worked the red carpet in a strapless designer gown.
