Rapper Lil' Wayne has pleaded guilty to a charge of attempted weapon possession and expects to receive a one-year prison term. He had previously pleaded not guilty to a different gun charge that carries a minimum 3 and a half year sentence. His trial had been set to begin on January 20th, but the rapper, born Dwayne Carter, agreed to a plea bargain after DNA evidence was ruled admissable yesterday in a Manhattan courtroom.
