Controversial rapper Kanye West has kept his promise of working with Justin Bieber by taking on Raekwon to remix on of the teen-sensation's songs.

Earlier this month, the two musicians exchanged a few tweets and the pair are now buddies.

Yeezy told Bieber: "Maybe we can do something together. Me, You and Raekwon."

Ever-humble Justin Bieber then replied: "Me, u, and the chef 2gether (sic) on a song = EPIC. Haha. Might sound crazy 2 u (sic) but even having this convo (conversation) is living the dream."

Kanye West has now revealed that he has remixed Bieber's 'Runaway Love' with rapper Raekwon.

Yeezy tweeted: “Finishing Justin Bieber Runaway Love remix too…don’t know when they gonna drop it but Raekwon’s verse is crazy!!!”
