Following Victoria Beckham's praise for her husband's "giant penis" on billboards for the Giorgio Armani underwear adverts recently, David has kindly returned the favour. During a trip to Brazil to open his latest Football Academy, the sports star wore a grey t-shirt with a black and white image of his naked wife on the front, alongside the slogan, "Protect the skin you're in."

 
Marc Jacobs, who designed the cotton tee, got fashion tongues wagging when he decided to use the Spice Girl in his most recent advertising campaign, shot by edgy photographer Juergen Teller.

 
But it's not just fashion that Ms Beckham and her new pal Jacobs are promoting: the t-shirt is being sold in Marc Jacobs boutiques to raise money and awareness for The Interdisciplinary Melanoma Cooperative Group at New York University. "Since we have moved to California, I have realized how important it is to practice safe sun for myself and to keep the skin of my three boys well protected as well", she was reported as saying.  So it's not just an excuse to show off that splendid bod, then, Posh?
