Reuters: The 28 dates on Madonna's just-concluded North American jaunt grossed about $91.5 million and moved about 550,000 tickets, according to tour producer Arthur Fogel, chairman of global music for Live Nation.

The venerable performer wrapped the North American leg of her Sticky & Sweet tour Wednesday in front of 50,000 people at Dolphin Stadium in Miami. She then headed to Mexico City for shows Saturday and Sunday.

Counting her European run, Madonna is at about $207.5 million in ticket sales and on a pace to hit about $282 million when the Mexico/South America leg of the tour wraps. That would make Sticky & Sweet the top-grossing tour ever by a female artist or solo artist.
