One of the tell-tale signs that a hip-hop artist is taking their acting career seriously is when they drop their rapper “stage name” and switch to their real name. Xzibit will now be using his real name of Alvin Joiner in the credits and publicity of the upcoming movie X-Files: I Want to Believe. He plays FBI Agent Mosely Drummy in a major role where he helps Mulder and Scully solve an unthinkable crime. Not only did Alvin slim down for the role but he shaved his head and even went through FBI training as well. X-Files: I Want to Believe hits theaters July 25th.
