Naomi Watts joins a galaxy of female stars posing nude for the 2007 cult Pirelli calendar.

Next year's calendar also features veteran sex symbol Sofia Loren, who first featured on magazine covers half a century ago, dressed up only in diamond earrings.

Other stars include Spain's Penelope Cruz, US star Hilary Swank and France's Lou Doillon, the daughter of singer-actress Jane Birkin.

The calendar portraits of Loren taken by Dutch photographers Inez van Lamsweerde and Winoodh Matadin are "very beautiful and will add to the myth of La Loren," said Loren's close friend Silvia Damiani, one of the privileged few to have already caught a glimpse of the latest Loren revelations.
The newspaper Corriere della Sera published test versions of the closely guarded pictures showing the star stretched out on a bed – but fully dressed in a black outfit and wrapped in a sheet.

Among the Naples star's screen triumphs was an appearance in a transparent negligee in her 1964 movie "Marriage Italian Style," and her striptease in front of fellow Italian Marcello Mastroianni in "Yesterday, Today and Tomorrow," reprised 30 years later in director Robert Altman's "Pret a Porter" (Ready to Wear).

Her Indian summer in the nude has divided Italy's showbusiness world.

"Sofia Loren is an icon, she can do whatever she likes," said statuesque actress Valeria Marini, herself a veteran of the nude photography front. Source
