Initial onsales for Madonna's upcoming Sticky & Sweet tour are off to a strong start, with weekend sell-outs reported in Paris (Sept. 20), Boston (Oct. 15) and Chicago (Oct. 26), followed by sell-outs in New York this morning. Performances at Madison Square Garden (Oct. 6-7) quickly went clean, followed by a third show now confirmed for October 11.

The tour will begin August 23 in Cardiff, Wales, and will play arenas and stadiums throughout Europe, including a number of cities where Madonna has not performed in the past 15 years, or ever. The tour begins in North America on Oct. 4 at the Izod Center in East Rutherford, N.J., with most U.S. dates going in sale May 24.

Live Nation Global Touring chairman Arthur Fogel is the worldwide producer of the tour.
