Mariah and Paula both fit this B.I., but then again neither is totally washed up. Mariah's pulled off a comeback unfortunately, and Paula's got the American Idol job. Plus, Mariah got discovered by Tommy Mottola who's not black.
But I'll go with Paula, since she did screw around with Jackie Jackson. I remember the story about Jackie's wife dragging Paula out of the car and beating her down when she showed up at the house to pick Jackie up. Gotta love those crazy Jacksons.
