In Seattle fans of Kanye West got even more than they paid for. While performing on Wednesday, West went of a profanity laced diatribe against his mentor and best friend, Jay-Z. Kanye aired out all of Jay Z?s laundry. He blamed their brewing beef on feuding streaming services. Between the Apple/Tidal turf war and Jay-Z apparently not calling Kanye after Kim was robbed at gun point, the two are apparently estranged. West even revealed that Kanye's kids have never played with Jay-Z's kids.
