Madonna's Sticky and Sweet tour is set to become the biggest-selling tour by a solo artist.
The tour finishes in Brazil at the end of the month, when the 50-year-old will have made a grand total of 185.7 million in ticket sales, beating the previous record of 127 million (set by her) on her 2006 Confessions tour.
The tour will finish in Sao Paulo with three nights between 18 and 21 December.
