MADONNA'S Sticky and Sweet tour is set to become the biggest-selling tour by a solo artist.
When it wraps up in Brazil at the end of the month, the singer would have raked in £185.7m ($282m) in ticket sales.
The 50-year-old held the previous record after her 2006 Confessions tour made £127.5m ($193.7m).
Tour producer Live Nation said the 28-date North American leg of the tour, which finished in Miami before 50,000 people at the Dolphin Stadium, sold 550,000 tickets and grossed £60.2m ($91.5m).
Her European run made her an estimated £136.6m ($207.5m) in ticket sales.
The tour, that supported the album Hard Candy, will finish in Sao Paulo with three nights from the 18th to 21st December.
