Ashanti gets her groove on as she headlines the fourth annual Pantene Pro-Voice concert in New York City on Thursday (performing hits like "Rock Wit U" and "What's Luv?"). The event also featured Canadian rocker Fefe Dobson and Marie Digby, the winner of the Pantene competition, which gives unsigned artists between the ages of 14 and 24 a shot at music stardom.
