Fayette County Sherriff's Office spokesman J Allen Stevens said that Ross, whose real name is William Leonard Roberts, had been processed and placed in the county jail, reported Billboard.
Stevens said that an officer stopped Ross and a passenger in his Bentley because the windows were tinted too darkly and infringed regulations.
The officer then "identified marijuana in his vehicle" because of the smell and arrested them, Ross having given consent for a deputy to search the car, Sherriff Barry H Babb later told CNN.
He has been charged with misdemeanour marijuana possession and a traffic violation. Because of the minor nature of the incident, Ross may make bail easily.
Ross, 39, was previously arrested in June 2014 in North Carolina, having failed to attend a court hearing related to a previous misdemeanour for marijuana possession dating back to 2011.
