Kanye West first got his big break as Jay-Z's producer, and the two eventually developed a close relationship.  But despite all the success they've shared, their relationship has gone through its ups and downs. As Kanye became more successful in his own right, sources say that Jay, who is much humbler and more reserved, grew annoyed at Ye's arrogance and ego. After Jay failed to appear at Kanye's 2014 wedding to Kim Kardashian, rumors began circulating about a strain in their relationship.  Kanye later confirmed this while ranting on stage during his Life of Pablo tour, making wild accusations about his former mentor. Jay later addressed the rant on his 4:44 album on the track Kill Jay-Z. The same year, Kanye left Jay-Z's streaming service Tidal, claiming they owed him unpaid fees. But despite the tension, it seems like they have since made up. The two moguls have been spotted out in public, and Jay even appeared on Kanye's 2021 album Donda on the song Jail. So, while they may not be as close as when they were first working on the Blueprint, it seems like they have patched things up and are still on good terms.
