Mary J. Blige as Brook Lynn

The alter-ego for the R&B star plays a role on Blige's album "The Breakthrough." The album credits list the Brook Lynn character as a guest star, and she arrives to spit nastier rhymes that one would associate with Blige. Like Beyonce's Sasha Fierce but predating her, Blige's Brook Lynn is a crazier, more wild soul.Stephen Lovekin, Getty Images
