This is quite a big deal - for Ke$ha!
Rihanna is hitting the road for a full out North American tour this summer.
This is RiRi's first-ever headlining tour of the U.S. and we think it's gonna be a risky outing. Will she be able to fill out those big arenas??? Definitely not if she has high ticket prices!
Rihanna is calling it the Last Girl On Earth tour, but she sure isn't the only gal to be seen.
Joining her on her musical romp cross the U.S. will be
flash-in-the-pan pop star Ke$ha, as well as rapper Nicki Minaj.
The girls will begin in Seattle on July 2nd, with a total of 25 shows across the nation, including a stop in El Lay on July 21. Tickets go on sale Friday!
