Victoria Beckham will strip down to her bare essentials for Marc Jacobs Spring/Summer 2008 ad campaign. The Spice Girl will appear nude on charity T-shirts designed by M.J. V.B was originally signed up to model the designer’s forthcoming spring/summer 2008 fashion line, but was then asked to get naked for the campaign, which aims to raise money for skin cancer charities.

A source tells The Daily Mirror:

“Victoria loves Marc’s work but 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 him down. The picture she and Marc have chosen is amazing – sexy but tasteful.”
