The Spice Girl has signed a deal to become the face of designer Marc Jacobs' Spring/Summer 2008 collection and he has persuaded her to be photographed naked with the image to be used on a range of his skin cancer charity T-shirts.
A source told Britain's Daily Mirror newspaper: "Victoria loves Marc's work but she wasn't entirely comfortable with getting naked.
"Marc went all-out to persuade her. And when she heard about what a great cause it was she knew she just couldn't turn it down. The picture she and Marc have chosen is amazing - sexy but tasteful."
