A judge sentenced Paris Hilton to 45 days in county jail Friday for violating her probation, putting the brakes on the hotel heiress's famous high life.

Hilton, who parlayed her name and relentless partying into worldwide notoriety, must go to jail by June 5.

She will not be allowed any work release, furloughs, use of an alternative jail or electronic monitoring in lieu of jail, Superior Court Judge Michael T. Sauer ruled after a hearing.

The judge, saying "there's no doubt she knew her license had been suspended," ruled that she was in violation of the terms of her probation in an alcohol-related reckless driving case.

"I'm very sorry, and from now on I'm going to pay complete attention to everything. I'm sorry, and I did not do it on purpose at all," she told the judge before he announced the sentence.

She was then ordered to report to a women's jail in suburban Lynwood by the set date or face 90 days behind bars. The judge's ruling excluded her from paying to serve time in a jail of her choice, as some violators are allowed to do.
