90s Hip-hop icons are coming back to collaborate once again. Lauryn Hill and Nas announced a joint North American tour for the fall. The ‘Ms. Lauryn Hill & Nas’ tour will head to 17 cities across the U.S. and Canada starting September 7. This isn’t the first time the pair worked together, as they collaborated on the 1996 hit song, ‘If I Ruled The World.’ Tickets for the tour will go on sale June 2.
