At this point, it appears that mentor-mentee and longtime friends and collaborators Jay Z and Kanye West aren't just watching the throne—they're competing for it. 

Friday morning, 'Ye announced his first headlining tour in five years, a two-month-long fall trek behind his arty-aggressive new album Yeezus, featuring hot Compton rapper Kendrick Lamar on opening duties. But the glory didn't last long: Less than an hour later, Hova responded by unveiling dates for a tour all his own in support of his blockbuster summer release Magna Carta Holy Grail (which itself dropped a thunder-stealing two weeks after Yeezus). Also, tickets for Jay's tour, aptly titled the Magna Carter World Tour, go on sale just one day before tickets for Kanye's Yeezus trek.

Jay's outing kicks off November 30 in St. Paul—dance off that Thanksgiving weight, Minnesota!—then crosses North America over 34 dates in December and January. It follows Hova's Legends of the Summer Tour with friend and collaborator Justin Timberlake, who recently ended his beef with Kanye; as you may recall, 'Ye dissed JT's The 20/20 Experience single, featuring a verse from Jay Z, in an onstage rant in London earlier this year: "I got love for Hov, but I ain't f-cking with that 'Suit & Tie,'" 'Ye said. But at the recent MTV VMAs, 'Ye and JT, who conveniently sat next to each other (good work, MTV), apparently settled the disagreement and may have even planted the seed for a future collabo.

Still, the drama appears omnipresent: Wonder how Kanye feels about Jay's wifey Beyonce kicking it with 'Ye's exe, Amber Rose, backstage at Hov's Philadelphia fest Made in America last weekend? Jay Z and Kanye West: It's apparently complicated, folks.
