The 'Hung Up' singer's flamboyant costumes - designed by Jean Paul Gaultier for her 'Confessions' tour - will reportedly be sold off to raise money to help AIDS victims in Africa.

A source told Britain's Closer magazine: "She has pledged money to AIDS charities since the beginning of her career. She's thinking about doing it through eBay, or maybe an auction house in London."

The singer has already pledged over ¡ê2 million to help orphans in Malawi.

She is reportedly also planning to visit the impoverished country later this year.
