While Britain's most public divorce is getting nastier by the day, Lady Heather Mills McCartney finds solace in posing naked for a sexy calendar that will be a part of the 'I Would Rather Go Naked Than Wear Fur' campaign.

If the rumor is true, the news will definitely affect Sir Paul more than a lot, especially considering that the special photo shoot took place on his estate, while he was out of the country. Heather is said to have struck poses in different naked postures and wearing more than 12 wigs, as she recreated the images of sexy icons such as Marilyn Monroe.

Everybody involved in the shoot had to be sworn secrecy, as the former model, now turned animal campaigner did not want the press to find out about the pictures. Sources said that she would be including them in a calendar for PETA, in the 2007 or 2008 campaign.

'She looked amazing and is justifiably incredibly proud of her body. And she wanted to show that, despite the stressful time she has been going through, she is determined to carry on with her life. She wanted to have some fun. She feels everyone has been attacking her and had a "what the heck" attitude. She wanted to do something vivacious and sexy and this seemed like the perfect idea', one of Heather's closest friends told the British 'The Sun'.

After doing the 'what the heck' thing and going through with the photo shoot, the same friend stated that Mills had a unexpected change of heart and thought that it would be best for her not to make the photos public at the time that her divorce is still on the roll. So, she asked the photographer and the persons involved not to leak the pictures with her naked to the press and, even more, not to reveal a single detail about the shoot to anybody.

It seems they all did just that, if the rumor turns out to be true.
