The Queen of Pop has donated one of her favorite pairs of Christian Dior pumps to a charity supporting gypsy child education.

In August, Madonna drew international attention by halting a concert in Bucharest and proclaiming that widespread discrimination against eastern Europe’s gypsies, also known as Roma, should end. Thousands of fans responded by booing the music legend.

The skyscraper gold heels, which are autographed by Madonna, will be sold at the Ovidiu Rom annual ball later this month, organizers said Tuesday.

“Madonna’s very mild comment regarding equality shone a spotlight on a common European attitude toward Gypsies,” says Leslie Hawke, president of Ovidiu Rom and mother of actor Ethan Hawke. “We’re thrilled to have her donation because she is such an icon of innovation and vigour and ‘can do’ spirit.”
