Get ready for a royal visit from the rulers of hip-hop. Kanye West and Jay-Z are embarking on a North American tour this fall in support of their upcoming album 'Watch the Throne.' Yeezy and Jigga will perform as the rap supergroup the Throne on their 21-city trek, which kicks off Sept. 22 in Detroit and wraps up on Nov. 3 in Boston.

In addition, the duo's LP 'Watch the Throne' will come later than expected. Their collaborative effort will hit iTunes exclusively on Aug. 8, while the physical copies will arrive in stores on Aug. 12.

Fans can cop pre-sale tickets on July 28 through Aug. 7 at Live Nation before they become available to the public on Aug. 8.

The hype surrounding 'Watch the Throne' has reached a fever pitch since West and Jay-Z released 'Otis' last week to mixed reviews. You can read PopCrush's thoughts on their soul-drenched swagger track, here.
