The world needs Kanye West: John Legend

Singer John Legend has praised Kanye West for being an "important talent" and believes the world "needs" him.

The 38-year-old 'All of Me' hitmaker hopes his friend, who was hospitalised earlier this year with exhaustion and sleep deprivation, is on the mend, reported Rolling Stone magazine.

"This is a very difficult life and a difficult business. I don't want to try to play pop psychologist, so I'm not gonna try to analyse what's happening with him. I just want him to do whatever he needs to do to feel better and to feel like he's ready to go again, because music needs him. The world needs him. I think he's such an important talent."
