Hey M Girls!
Rihanna and Ke$ha are going on tour this summer in a city near you! Rihanna will be headlining the tour called "Last Girl on Earth." "We've never done a tour to this capacity. The production is unbelievable and the costumes, we just took it to a whole new level," Rihanna says.
Other stars like rapper Nicki Minaj, Mariah Carey, Ludacris, Lil Wayne, and Usher will be making appearances randomly throughout the months of tour.
The tour kicks off on July 2 in Seattle, WA and will run through to August 25 in Chicago, IL.
