Mariah Carey is selling one of her dresses on eBay

The 'Hero' singer has put a hot pink, fishtailed asymmetric frock onto the auction website to raise money for breast cancer charity Susan G. Komen for the Cure.

The gown was created by Julian Contreras as part of a competition where the singer asked fans to design a dress inspired by her Deicious Pink fragrance. It is one of only three in existence.

Mariah was last seen wearing the dress on a dinner date with husband Nick Cannon in Calfiornia in April.

The close-fitting dress will be listed until May 30.

Mariah is not the only celebrity to be selling her property on eBay.

Gwyneth Paltrow recently offered garments - including a Burberry dress and a Topshop trench coat - on the auction website, with all funds going to the Robin Hood Foundation which helps fight poverty in New York.

Jessica Alba has been selling her daughter's old clothes on eBay.

The 'Sin City' star recently placed a number of items on the bidding website in aid of charity, including some of 11-month-old Honor's old garments, Hello Kitty rain gear and a limited-edition Maclaren Juicy Couture Ruder Stroller.

All proceeds from Jessica's sale went to the Clean Water Initiative, which aims to provide all babies with access to fresh water.
