Kanye West's spirit singing

Kanye West thought avoiding ghosts would improve his singing.

The 'Stronger' star - who has come under criticism for ditching rapping for singing on his current album '808s and Heartbreak' - was left bemused after asking Franz Ferdinand frontman Alex Kapranos for vocal tips backstage at KROQ's Almost Acoustic Christmas concert in California.

A source revealed: "Alex told him not to have conversations in noisy places, to not smoke, and to stay away from the spirits, to which Kanye said, 'Spirits? Like, ghosts?' "

Kanye recently insisted he doesn't care that his new album may have cost him some followers.

He said: "On this album I might have lost some rap fans, but what I gained is a new perspective on life and just the ability to do what you want. Do what makes you feel good and if people want to award that, it's cool."
