A judge has ordered Paris to jail for 45 days! She will begin her sentence on June 5. TMZ has video of the heiress leaving the court house.

An emotional Paris, with tears welling up in her eyes, told the judge moments before the decision "I'm sorry, I'm sorry." Witnesses inside the courtroom say that Paris' parents, Rick and Kathy Hilton, were both visibly upset as the sentence was handed down. Kathy, we're told, was especially distraught.

The judge called out her rep Elliot Mintz in court, describing his testimony as "completely worthless." He also told Paris that he did not believe that she was unaware of her license suspension, adding that she had paperwork in her car stating that her license was suspended.
