LOS ANGELES - Screaming and crying, Paris Hilton was escorted out of a courtroom and back to jail Friday after a judge ruled that she must serve out her entire 45-day sentence behind bars rather than in her Hollywood Hills home.

“It’s not right!” shouted the weeping Hilton, who violated her parole in a reckless driving case. “Mom!” she called out to her mother in the audience.

Hilton, who was brought to court in handcuffs in a sheriff’s car, came into the courtroom disheveled and weeping, hair askew, sans makeup, wearing a gray fuzzy sweat shirt over slacks.
