Dr. Dre is to release his new album before the end of 2008.

The rap legend will release 'Detox', his third (and reportedly final) album after almost four years of preparation.

The album features guest slots from the likes of Lil Wayne, Jay-Z, Nas and other hip-hop luminaries.

Dre plans to return to producing after its release, and is expected to take the helm on Eminem's sixth album, which is rumoured for release in late 2008/early 2009.
