US rapper Nas has recorded a song for Dr Dre's forthcoming studio album 'Detox'.
The album, which will be Dr Dre's first new release since 2001, will also feature Eminem, 50 Cent and R Kelly.
Speaking to Billboard about his collaboration, Nas said: "I did a joint, I think it’s crazy.”
The rapper added that he hoped to one day work with Dr Dre on a full album, describing his fellow hip-hop star as “best producer of all time”.
As previously reported on Gigwise, Dr Dre was recently forced to put work on 'Detox' on hold in order to produce Eminem's new album, 'Relapse'.
At present, it's not clear when 'Detox' will be released.
