Sienna Miller, Kate Moss and Keira Knightley have all donated a pair of shoes to help raise money for charity.

The trio of beauties have given their beloved footwear to an auction for the Small Steps Project, an organisation which provides food and clothing for children who work on some of the world's biggest landfill sites.

Speaking about the Stefanel sandals she parted with for the cause, new mother Sienna said: ''These shoes were given with love. I loved dancing the night away in them and hope they can bring as much joy to someone else. It is a privilege to be able to donate to such a worthwhile charity.''

Gemma Arterton, Margherita Missoni and Joanna Lumley have also donated their heels, while Russell Brand, Will Ferrell and Ben Stiller have each handed over a pair of trainers.

Last year's successful inaugural auction, which raised over £20,000 and the 2012 auction will be held at Jalouse in London on October 11.
