The tour will promote her latest album "Confessions on a Dance Floor," which has sold about 1.4 million copies in the United States since its November release.

Contrary to speculation that the outing would play smaller venues than usual, the "Confessions Tour" will visit arenas and stadiums throughout the world. Dates are on tap through September 3 in Amsterdam. A press release said Madonna would also play Tokyo and Osaka, but no dates were indicated.

Madonna was last on the road in 2004 with her "Re-Invention Tour," which grossed $125 million, according to Billboard Boxscore.

She will warm up for the new tour with a previously announced April 30 date at the Coachella Valley Music and Arts Festival in southern California, the first festival appearance of her career.
