The new Madonna.com newsletter announces two extra presales for concerts of the Sticky & Sweet Tour and also contains an interesting tidbit for North American fans.

• A second show at Chicago’s United Center on October 27 has been announced – with a presale for members of Madonna’s official fanclub beginning today.

• The Icon presale for the second show at the Stade de France in Paris on September 21 will begin on Monday, June 2.

Today also marks the start of an extensive bunch of Icon presales for the concerts in
