The Oscar winner has been wearing the yellow Rupert Sanderson-designed shoes to red carpet events linked to her hit new animated movie and she signed them and put them up for sale last week (ends10Jul15).

The shoes went under the hammer for just over $42,000 (£28,000) and the actress agreed to match the figure, so that officials at the Art + Practice charity would pick up an $84,000 (£56,000) cheque.

Speaking to, Bullock, who voices villain Scarlet Overkill in the film, said, ''When you discover people who are truly giving back, and taking care of our community, I think it's our duty to support and take care of them in return."
