Good to hear she is giving the money back to a charity!
The singer had originally purchased the 1921 painting "Three Women at the Red Table" at a Sotheby's auction house sale for $3.4 million in 1990.
Proceeds from yesterday's sale will benefit Madonna's Ray of Light Foundation, supporting girls' education projects in Afghanistan, Pakistan and other countries.
"Thanks to everyone who helped make it happen!" Madonna wrote on her Facebook page.
