Stella McCartney, Nicole Farhi and Cheryl Cole were just a few of the celebrities to get involved in an artistic charity challenge.

The celebs all drew hare-shaped pictures, meant to express themselves, which are now up for auction as part of HareStyling, all in aid of Great Ormond Street.

Celebrity Haridresser Michael Van Clarke came up with the idea of drawing on celebs to raise money for the hospital after his daughter was given a lifesaving operation when she was two.

She is now 15 and drew her own hare to help raise funds for the two new operating theatres needed. All the pieces on auction can be found here . And to have a very own celebrity harepiece bid here .
