The duo's Elly Jackson said the rapper-producer first heard 'In For The Kill' after the Skream remix was played on the TV show, 'Entourage'.

She told BBC Newsbeat: "He got really excited about the track which is obviously really complimentary.

"He did something with it and then sent it to us and said can he use it for his record and we said, 'Yes.'"

'Detox' is Dr Dre's follow-up to his 1999 album, '2001'.

The album, which also features a guest appearances from Eminem and Jay-Z, has yet to be given a release date.
