One of the most hyped about hip-hop albums these days is 50 Cent's Street King Immortal. While the album isn't slated for release until next year, guest appearances from Dr. Dre, Alicia Keyes, Chris Brown, Ne-Yo and Too $hort are already confirmed.
Adding to the growing list is 50's mentor Eminem and Maroon 5 singer and The Voice judge, Adam Levine. Both will be featured on the upcoming single "My Life" which will be released via iTunes on November 27. [Rap-Up]
