Eminem has confirmed through a tweet that he will release his ninth studio album, ShadyXV. Fuse reports: The Shady XV trailer (linked to in the first tweet above) doesn't reveal much at all, though it does flip through some images of Eminem's past (including some D12 snapshots and a 50 Cent cameo or two). Who knows: His ninth album could very well be a retrospective piece that offers up both new collaborations (a la "Guts Over Fear") and greatest hits alike.
