There is definitely something amiss in Jay Z and Kanye's relationship.

'Ye confirmed the rift during a recent show in Seattle when he complained about Hov both by name and subliminally, and demanded the DJ skip forward when the Throne hit 'Niggas In Paris' started to play.

'Ye seemed especially perturbed that their kids don't play together.

Now the New York Post is reporting that there's a specific reason North West and Blue Ivy aren't friends: Hov can't stand West.

A music insider told us that the rappers’ friendship was never what it seemed. “Jay can’t stand him,” said the source. “He looks at him as this crazy, eccentric motherf - - ker he can tolerate in small doses. Kanye is a nut job. Everyone knows that.” The source said of the tour for the duo’s blockbuster 2011 album “Watch the Throne” that Jay Z “tolerated” West because “there was so much money to be made. Jay was like, ‘I’m gonna knock this out. We’re going to do a tour to bring in millions of dollars. I can tolerate that.’ ”
