Eminem's long-delayed mixtape, "The Re-Up," is reportedly set for release next month.

According to The Detroit News, "The Re-Up" will serve as a memorial to D12 member Proof, who was shot and killed at a bar near 8 mile in Detroit, MI this past April.

The mixtape will include the songs "Things Need to Change" and "Last Words (R.I.P. Proof)," which both discuss the slain rapper's death. Obie Trice, D12, Busta Rhymes, Dr. Dre and Trick Trick will also appear on the anticipated project.

In related news, Eminem will be featured on Akon's forthcoming album, Konvicted. The Detroit bred rapper and the Senegalese crooner recently shot a video for the album's first single "Smack That."

Due in stores on December 12th, Konvicted also features appearances from Snoop Dogg and Styles P.
