Eminem is going to be on Lil'Wayne new album "Rebirth". On a track called "Drop The World". Its been Weezy wish for a long time to do a track with him and Eminem. But the day "Rebirth" drops is the same day as Eminem "relapse: The Refill". I found this information on rapbasement so it probs true but the track list for rebirth is not amazon yet.
