Eminem and Mariah Carey just can't seem to stop griping about each other. The latest round in their ex-lovers' quarrel gets played out in OK! Magazine (via Gatecrasher), which says that Eminem's new album is mining his fling with Mariah six years ago for material. "There is more than one track that goes into really specific, intimate detail about what went on between Em and Mariah," says an "insider." In fact, Mariah's so mad about the new tracks that she's asked the head of her record label to intervene, and wants to sue Eminem for slander.
