N.C. Gen. Stat. § 14-7.11
When an indictment charges a violent habitual felon with a violent felony as provided in this Article and an indictment also charges that the person is a violent habitual felon as provided in this Article, the defendant shall be tried for the principal violent felony as provided by law. The indictment that the person is a violent habitual felon shall not be revealed to the jury unless the jury finds that the defendant is guilty of the principal violent felony or another violent felony with which the defendant is charged. If the jury finds the defendant guilty of a violent felony, the bill of indictment charging the defendant as a violent habitual felon may be presented to the same jury. Except that the same jury may be used, the proceedings shall be as if the issue of violent habitual felon were a principal charge. If the jury finds that the defendant is a violent habitual felon, the trial judge shall enter judgment according to the provisions of this Article. If the jury finds that the defendant is not a violent habitual felon, the trial judge shall pronounce judgment on the principal violent felony or felonies as provided by law.
