Wayne, 27, whose real name is Dwayne Michael Carter Jr., chose not to speak at his sentencing on Monday, the New York Post reports. With good behavior, he could be out of prison in eight months.
After initially pleading not guilty to gun possession after a July 2007 arrest, Wayne changed his plea to guilty in October in exchange for a reduced 12-month sentence.
Wayne had had his sentencing postponed twice in the past month – once so he could have dental work done, and once because of a fire in the courthouse basement.
He recently tried to put his ordeal in perspective, telling Rolling Stone: "I look at things as 'Everything is meant to be.' I know it's an experience that I need to have if God's putting me through it."
