Katy Perry took to Facebook today to tell her millions of friends that she will start the U.S. portion of her California Dreams tour June 7 in Atlanta. The 41-city outing, sponsored by Schick Quattro for Women (that’s a razor), ends Aug. 14 in her hometown of Santa Barbara, Calif.

The international tour starts Feb. 20 in Lisbon, Portugal and will travel through Europe, U.K. Australia and Japan before she comes to the U.S.

The tour supports Perry’s two albums, 2008’s “One of the Boys,”  and her newest effort, 2010’s “Teenage Dream,” which has sold more than 5 million copies worldwide since its August release, according to her label EMI.  Her song, “California Gurls” featuring Snoop Dogg, was the top selling single in the U.S. last year, moving close to 4.4 million copies.

Perry is up for four Grammys this year, including the coveted album of the year award for “Teenage Dream.”
