So much for pink ribbons.

Singer and breast cancer survivor Kylie Minogue, pregnant supermodel Claudia Schiffer, and actress Sienna Miller have joined forces and dropped trou to give cancer awareness a dose of sex appeal in the stylish new Fashion Targets Breast Cancer 2010 campaign.

Shot by famed photographer Mario Testino, the sultry black-and-white images feature the three blonde beauties naked underneath silk bull's-eye-print sheets.

Their come-hither looks and bed-head 'dos are for a good cause: The FTBC campaign promotes the UK charity Breakthrough Breast Cancer's special collection of trendy black-and-white fashions from British retailers including Topshop.

Purchase any item and 30 percent of the sale will go toward helping raise breast cancer awareness.

"This is feel-good fashion at its best," the charity says in a statement.

Indeed. In fact, we're already inspired -- to do some good, and to, um, stop hitting the sheets in sweatpants and hair rollers.
