Kanye West has revealed that he is putting the finishing touches to a remix of Justin Bieber's song 'Runaway Love'.

The rapper's remix will include a verse from Wu-Tang star Raekwon.

"Finishing @JustinBieber 'Runaway Love' remix too,” West wrote in an update on Twitter today (August 19).

“Don't know when they gonna drop it but Raekwon's verse is crazy!!!”

West and Raekwon began working on the song after the rapper struck up a relationship with Bieber on Twitter.

Raekwon later told XXL magazine: "When you got these kinda talents merging together to do something exciting, I think it's something that's gonna make the fans check it out."

West has been working with Raekwon on his forthcoming studio album, which is due to arrive in November.
