French photo magazine published a photo of Russian supermodel
Natalia Vodianova naked during her pregnancy.
Natalia is married to British real estate heir Justin Portman. The couple had their first child in December 2001, second one in March 2006 and third one in September 2007. I am not sure during which pregnancy she posed naked.
