Kanye West’s epic stage rant against Beyonce and Jay Z has sparked speculations that not all is well between the Wests and the Knowles. A new report suggests that the music mogul is not happy with Yeezy.

“Jay can’t stand [Kanye]. He looks at him as this crazy, eccentric motherf***er he can tolerate in small doses. Kanye is a nut job. Everyone knows that” an insider allegedly told Page Six. Hollywood Life reports that the rappers are not as personally close as fans think they are. And Kim Kardashian’s Paris robbery case was just the last straw in escalating their tension before the public.
