The rumoured new Eminem single 'Crack A Bottle' is now available to listen to online.

The song is the first new material of the rapper's since his self-imposed hiatus, and features the lyrics: "So crack a bottle, let your body waddle / Don't act just like a sloppy model, you just hit the lotto." It's believed to be the first single from new album 'Relapse', due this year.

An unfinished version of the song leaked late last year, but it didn't feature guest appearances from both 50 Cent and Dr. Dre.

The final version features both rap heavyweights weighing in to give Mr. Mathers a hand, and can be heard here now.
