50 Cent has revealed his hip-hop pal Eminem is recording a secret new album.

The rapper is supposedly retired from the game, but - surprise, surprise - he has been recording tracks for an upcoming fifth long player.

50 Cent tells Blender magazine, �He's got a new album coming. He's not gonna tell people that, but he's making new music.

�I've heard a few songs, and it's hot. He won't tell nobody he's working on a new album, but I'll tell you: he's working on new music."
