Britney Spears will kick off a world tour June 17, starting at Sacramento’s Power Balance Pavilion. The first leg ends  Aug. 13 at Toronto’s Air Canada Centre.

Spears’ rumored tour was confirmed this morning at “Good Morning America,” which featured taped pieces of Spears performing in San Francisco Sunday night. Spears’ new album, “Femme Fatale,” drops today. Read our review here.

Even before the first ticket for the Live Nation-produced out is sold, however, there seems to be some controversy. Touring partner Enrique Iglesias has already dropped out. Billboard reports that Iglesias, who is undergoing a bit of a career resurgence himself, was to have his own complete production, an unusual move for a support act. More as the story develops.

Spears last toured behind her 2008 album, “Circus.” The 2009 tour grossed $120 million over 84 shows, according to Billboard.

In other Spears news, she will “guest host” Wango Tango, the annual concert put on by Los Angeles’ Top 40 station KIIS. This year’s concert will take place May 14 at the Staples Center. No word on whether Spears will perform, but we doubt it since promoters no doubt want to save the excitement for her concert at the same venue two months later.
