MTV just announced that her “Last Girl On Earth” tour will begin on July 2 in Seattle and will make 25 stops all over the US. The road show ends on August 25 in Chicago. View the complete list of tour dates here.

What can we expect from RiRi’s summer tour? For one thing, newbies Ke$ha (who badly needs a promotion from being a “newbie”) and Nicki Minaj are the opening acts. Fans can also look forward to a bigger production. “We’ve never done a tour to this capacity,” Rihanna said in an interview with AOL. “The production is unbelievable and the costumes… we just took it to a whole new level. Visually and sonically it’s going to be a big step up from the last time.”

Tickets will go on sale at LiveNation.com on Friday, April 9, so mark you calendars!
