A criminal complaint was filed against Paris Hilton's boyfriend Thursday afternoon. RadarOnline.com reports that Cy Waits, also known as the heiress's arm candy, could be convicted of a felony charge and might even face jail time as a result of his August 2010 arrest.

On Aug. 26, 2010, Paris and Cy were pulled over in Las Vegas. Officers claimed the Cadillac SUV which Cy was driving had the smell of marijuana coming from it.

Paris' beau was then arrested on suspicion of driving under the influences of alcohol or drugs, and Paris faced the same charges after cocaine was found in her purse.

Paris ultimately struck a plea deal and received two six-month suspended jail terms, $2,000 in fines, 200 hours of community service and required entry into a substance abuse program.
