Paris Hilton: 45 DAYS IN JAIL!!!

Paris Hilton arrives 18 minutes late to her court hearing in downtown Los Angeles on Friday afternoon.

The heiress is currently testifying at Metropolitan Courthouse on her own behalf and could be thrown into jail for 45 for violating her probation for an alcohol-related reckless driving conviction.

Paris, 26, pleaded no contest to reckless driving back in January and was sentenced to 3 years probation, alcohol education and $1,500 in fines.

UPDATE: Paris was just sentenced to 45 days in jail, starting June 5 at the Century Regional Detention Facility (CRDF).

“I’m sorry, I’m sorry,” Paris said moments before Judge Michael T. Sauer made his decision.
