Kanye West is making a ''movie of his life'' which he thinks will be a piece of ''controversial art''.

The 40-year-old rapper - who has children North, four, and Saint, 23 months, with wife Kim Kardashian West - has spent years being followed by camera crews for his own project, but he reportedly insists it's as far away from his spouse's show 'Keeping Up With the Kardashians' as possible.

A source told The Sun Online: ''Kanye is very much still filming the documentary about himself. Kanye's documentary is being crafted as a 'work of controversial art', or the opposite of reality TV and 'KUWTK'.

''Basically he wants to make the movie of his life - but just about him and his work, not Kim and his family life.

''His vision is that it's going to be a cutting edge and 'real' documentary - all directed and produced by him. Kanye thinks this is the ultimate in reality TV - it's real life, and never been done before he says.''

The 'Famous' hitmaker has made nothing off limits to his camera crew, with his personal and professional life all captured on film.

The source continued: ''He's been filming for a few years - has thousands of hours or footage - of him at work, at home, at events, talking to the camera, private moments and public moments. Everything from the last few years.''

When Kanye has made his rare appearances on 'Keeping Up with the Kardashians', he's been allowed to approve the cuts before they air, but it seems his 37-year-old wife won't be given the same editorial control over his documentary, much to her concern.

The source added: ''Kim's worried he'll end up being made fun of - and that she won't get final edit over the documentary like she does with the reality show, where she's a producer.

''She wishes he'd just come on 'KUWTK' and show fans more of what he's really like off stage, bring their kids on the show and let people into their lives. But he always says he doesn't like the way it's filmed and feels uncomfortable on the show.''
