A pair of Spacey's black leather Prada footwear is up for grabs in the fundraiser for Macmillan Cancer Support, along with the Grease beauty's black and white pumps.
The In Their Shoes event also sees lots from Aussie singer Kylie Minogue, who has handed over signed sequined Moschino wedge sandals, and former Sporty Spice Melanie Chisholm, who offered up a pair of her Puma trainers.
Rod Stewart, Cindy Crawford and Simon Le Bon have also donated to the auction, which finishes later this month (Nov09).
