Kanye West 'Disappointed' Over 'Mama's Boyfriend' Single Leak

Kanye West is said to be 'disappointed' after his new single leaked online.

The track, entitled 'Mama's Boyfriend', emerged on various blogs and websites this yesterday (June 14).

A statement from Def Jam records said: "The version of the Kanye West recording "Mama's Boy" that arrived on blog sites earlier this week is entirely bogus and unsanctioned, and violates the artist's creative intentions. As is often the unfortunate case, an unknown party or parties got a hold of Kanye West's vocal track and added their own soundbed to it, effectively and falsely releasing it as a Kanye West track from the My Beautiful Dark Twisted Fantasy sessions.

''The result in no way resembles the final song Kanye West intended his fans to hear, and he is deeply disappointed that one of the most personal, meaningful and special songs he has ever written would reach people in this way. Needless to say, measures are being taken to identify and prosecute the persons responsible for leaking this material."

'Mama's Boyfriend' is thought to have been recorded for Kanye West's latest album 'My Beautiful Dark Twisted Fantasy' but was left off the final cut.

In the track, which West performed earlier this year at an exclusive Facebook event, discusses issues surrounding his mother and many of her past boyfriends.

Meanwhile, Kanye West will headline this year's Coke Live festival in Poland, it has been confirmed.
