Eminem’s collaboration with Pink, entitled ‘Won’t Back Down’, has leaked online.

The track, taken from the rapper’s new album ‘Recovery’, was produced by DJ Khalil.

The song sees Pink perform the chorus, while Eminem raps a series of vitriolic verses.

His lyrics include the line: “Girl, shake that ass like a donkey with Parkinson’s / Make like a Michael J Fox in your jaws playing with an exersketch.”

Speaking about the collaboration earlier this week, Eminem said: “When I did the song that I did with Pink, I laid my parts first and kind of heard her on the record and felt that she would smash this record.”

'Recovery', which is the follow-up from 2009's 'Relapse', is released on June 22.
