Everybody knows Kanye West is not the most humble person in the world, but when he declared himself to be the ‘greatest living rock star’, some thought he’s taken things too far. In the video below, Slipknot’s front-man Corey Taylor delivers a not-so-kind message to Kanye. ‘You are not the greatest living rock star. The fact that you had to tell people that, kinda says it all,’ he says. ‘You remind me of the guy who brags about p***y’, Corey added. ‘They never get as much as they brag about.’ Ouch! That’s gotta hurt.
