'Till The World Ends' pop superstar Britney Spears has revealed that the handcuffs and feather boa she used on her 'Femme Fatale' tour will be auctioned off for a worthy cause.

Writing on her official Twitter page this evening (June 21), the superstar explained that money raised from the sale of the two props (pictured left) will benefit an organisation called Soles4Souls:

"I always had so much fun with the boa & handcuffs on the Femme Fatale Tour every night! You guys remember right?! Now u can bid on the boa & handcuffs from the tour & help support @soles4souls...such an amazing cause!"

The mission statement on Soles4Souls' website explains that it is "dedicated to fighting the devastating impact and perpetuation of poverty."

"The organization advances its anti-poverty mission by collecting new and used shoes and clothes from individuals, schools, faith-based institutions, civic organizations and corporate partners, then distributing those shoes and clothes both via direct donations to people in need and by provisioning qualified micro-enterprise programs designed to create jobs in poor and disadvantaged communities."
