Paris Hilton's ex-boyfriend has a court date Wednesday to take a plea deal to settle criminal drug charges stemming from a Las Vegas Strip traffic stop with the celebrity socialite last year.

Cy Waits, 35, a former Las Vegas nightclub manager, didn't appear in court Monday while his lawyer, Richard Schonfeld told Las Vegas Justice of the Peace Bill Kephart that an agreement had been reached in the case.

Schonfeld didn't provide details. He said outside court he couldn't disclose terms ahead of time. Prosecutor L.J. O'Neale wasn't immediately available for comment.

Waits could face up to four years in state prison if convicted of a felony charge of being under the influence of a controlled substance, and less than a year in the Clark County jail in Las Vegas on misdemeanor marijuana possession and driving under the influence charges.

Waits was arrested Aug. 27, 2010, after a police officer reported seeing and smelling a "vapor trail" of marijuana smoke wafting from a black Cadillac Escalade with Waits at the wheel.

Hilton, a passenger in the vehicle, was arrested after police said a small bag containing 0.8 gram of cocaine fell from her Chanel purse as she reached for a tube of lip balm.

Hilton, 30, pleaded guilty last September to misdemeanor cocaine possession and obstruction charges. She is serving a year of probation.
