Britney Spears is back, y’all! And why the hell not? After cleaning up her act, winning three MTV Video Music Awards and her upcoming album release, Brit is back on top and planning a 2009 world tour.

Britney Spears hasn’t been on tour since 2004′s “The Onyx Hotel Tour,” which fizzled due to a knee injury.

Britney Spears confirmed the tour details in a Z100 radio interview yesterday, saying she would “definitely” be touring in 2009 and “probably around the world.”

Britney Spears’ newest album, “Circus,” is set to hit stores on December 2.
