The UK edition of Cosmopolitan has long been famous for its racy male centerfold spreads, but these images of a naked Prince William and Harry celebrating victory in a polo match, their modesty hidden by nothing more than a strategically placed trophy and a towel, look set to become legendary.

Too good to be true? Well, yes. If the ‘William’ and ‘Harry’ look a little irregular, then that’s because they are in fact lookalikes shot by artist Alison Jackson. The pictures were specially commissioned by Cosmo as part of the magazine’s 40th birthday celebrations. The cheeky snaps are also promoting men’s cancer charity, Everyman.

An Everyman spokesperson said, "Every man is extremely grateful for Cosmo’s ongoing support and for turning what could just be innocent eye candy into a potentially life-saving message. Women are the gatekeepers of men’s health and Cosmopolitan has been instrumental in promoting the importance of checking for signs of testicular cancer."
