Victoria Beckham has agreed to appear naked on charity T-shirts designed by Marc Jacobs.
The Spice Girl will be the face of Jacobs' Spring/Summer 2008 collection, according to the Mirror.
Julianna Moore, Dita Von Teese and Naomi Campbell stripped off for his T-shirts in 2006 to raise L30,000 for a skin cancer charity.
Talking about Posh's decision, a source said: "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."
