Paris Late for Very Important Date

UPDATE: Paris has arrived in court, 18 minutes late. We'll give you the blow by blow as it happens.

Paris Hilton has not exactly figured out how to win friends in high places. She's late for today's court appearance where a judge could revoke her probation and throw her in the pokey for 45 days.

The courtroom is filled with prosecutors, defense lawyers, the judge, nine deputies....but no Paris.

We're told she's moments away. EIGHTEEN minutes late and counting. Stay tuned. Could it be another slow-speed chase???
