Claudia, Sienna and Kylie strip!

Yves Saint Laurent - PFW - Ready To Wear - Fall/Winter 2011 - Front Row Kylie Minogue, Sienna Miller and Claudia Schiffer have all stripped off for photographer Mario Testino to launch a breast cancer charity campaign.

The worthy campaign is especially close to Kylie’s heart as she beat the killer disease herself just 4 years ago. The singer was draped in just a silk sheet sporting the logo of Fashion Targets Breast Cancer 2010 campaign.

The girls are hoping to help raise 1 million pounds and awareness of the disease.

Shops, including Marks and Spencer and TopShop, will donate at least 30 per cent of the price of some clothes to the cause.
