Eminem has pleaded no contest to two gun-related charges, less than two weeks after he was sentenced to two years probation on a separate charge of carrying a concealed weapon. Eminem, whose real name is Marshall Mathers III, was charged in a Michigan court with carrying a concealed firearm and brandishing a weapon during an argument with the road manager of the band the Insane Clown Posse. Sentencing is scheduled for June 5. He could face up to five years in prison.
