Madonna starts her tour on August 29th and she will visit places she hasn't in over a decade!
As you know, this time she will only do arenas, and the tour dates are coming up today!

The tour starts in Miami's American Airlines arena and will continue through North America until October. After 25-30 shows there, Madonna will visit Europe until December, for another batch of 20-25 concerts. Additional dates likely to be added as certain shows sell out.

January and February 2016 will see the Rebel Heart tour in Asia and Australia, and those dates will be announced at the end of March 2015.
Tickets go on sale March 9 and will cost more or less the average for a Madonna tour.

It is still unclear who will her opening act be, although it is probably gonna be a DJ.
