Rapper Kanye West has risked alienating his fellow stars by alleging "90 per cent" of famous faces are not interested in the good causes they support and are only speaking out to boost their finances.

The controversial hip-hop star is adamant most actors and musicians are "controlled" by their desire to make money and are not interested in using their fame to improve life for others.

He also admits going public with the accusation could cause him to be shunned by his celebrity peers but insists he does not care if his reputation is harmed.

West, who is married to reality TV star Kim Kardashian, tells Q magazine, "I just think there's a lot of celebrities that are completely controlled by their finances. You could literally tap them on the wrist and say they lost five dollars and they'll fall to the floor and beg for at least four of the dollars back. So when people expect a celebrity to do or say anything you're talking to the wrong group of people. They won't use their voice for the people. They'll only use their voice for money.

"Print it as loud, as f**king loud, as you want to. Print it. And I don't care what parties I don't get invited to afterward. Ninety per cent of celebrities only use their voice for the purpose of making money for themselves."
