Jessica Simpson, Kelly Clarkson and Leann Rimes are among the stars who have raided their closets and donated shoes to an auction in aid of an arts program.

Clarkson has handed over the Jimmy Choo stilettos she wore to sing the U.S. National Anthem at last year's (12) Super Bowl, while pregnant pop star Simpson has offered up her designer D'Orsay pair to the Kick Up Your Heels sale in support of New York's Lancaster Opera House's Summer Theatre Camp.

Rimes has autographed a pair of sparkly Christian Louboutin slingbacks and actresses Gillian Anderson, Joan Collins, Mayim Bialik and Melissa Joan Hart have also boosted the auction with their footwear.

In a post on her page, Hart writes, "Foot fetish? Shoe lover? Check out my slightly worn heels on sale for a good cause at Kick Up Your Heels."
