Rapper and reality TV star Nelly is facing felony drug charges after being arrested in Tennessee.

Tennessee Highway Patrol said in a news release that Nelly, whose real name is Cornell Haynes, was pulled over at 9:20am on Saturday because the bus he was riding in failed to display a US Department of Transportation and International Fuel Tax Association sticker.

According to the release, troopers smelled marijuana when they reached the bus.
