Rihanna‘s been popping up on a few major stages–like at the Kids’ Choice Awards–lately, and pretty soon America will be seeing a lot more of the Barbadian beauty on her just announced “Last Girl on Earth” tour. The “Rude Boy” singer is kicking off the run in Seattle on July 2, with pop singer Ke$ha and Young Money rapper Nicki Minaj as opening acts. The young trio will perform at 25 locations, including New York’s Madison Square Garden on August 12, finishing up in Chicago on August 15.
