Rihanna will kick off her biggest tour yet when she hits the road in the U.S. on July 2 at the White River Amphitheater in Seattle, Washington. Joining Rihanna on the "Last Girl on Earth"  outing will be Ke$ha and Nicki Minaj.

Rihanna has the No. 1 song on the Billboard Hot 100 this week with “Rude Boy,” the third single, but first major hit, from her 2009 album “Rated R.”
 
I interviewed Rihanna earlier this year during her AOL Sessions taping and she couldn’t wait to get on the road. "We’ve never done a tour to this capacity, which I’m very excited about. The production is unbelievable," she said. "The costumes, we just took it to a whole another level. Visually and sonically it’s going to be a big step up from the last time. We just keep growing, every time, keep growing and this time it’s going to be a massive, massive production that I cannot wait for.”
