Madonna will auction off items from her record-breaking MDNA Tour to benefit Sandy victims, sources tell us. We hear her Madgesty will sell items that may include the majorette costume and the caged basque she wore onstage, as well as props for the set (but not the gun she used for the gig). After Sandy, Madge visited the Rockaways with Klaus Biesenbach, MoMA’s chief curator and director of PS1. Then, the next night, she stripped onstage while urging fans to donate to the relief effort.
