Kate Moss revealed her derriere and her strategically placed wing tattoos on the cover of May's Brazilian Vogue. The sexy image and accompanying spread were shot by Mario Testino, a longtime confidant and collaborator of the 37-year-old supermodel, during a trip the pair took to Sao Paulo two months ago. The renowned photographer has lots of famous friends — he also snapped Kate Middleton and Prince William's engagement pictures and was a guest at this morning's royal wedding! Mario may have yet another set of high-profile nuptials to capture on film soon. Kate is rumored to be tying the knot with her longtime boyfriend, The Kills frontman Jamie Hince, this Summer.
