Stella McCartney has wooed Amber Valletta away from Tinseltown — where she's making her mark as an actress — back to the fashion glossies. Valletta will be featured in McCartney's spring ad campaign, shot by Inez Van Lamsweerde and Vinnodh Matadin at London's Number Eleven Cadogan Gardens hotel in November. "As far as I'm concerned, it's time for a bit of Amber," declared McCartney, who assisted on the shoot while she was eight months pregnant. Valletta replaces Kate Moss, who has appeared in past McCartney campaigns. The ads, art directed by M/M Paris, will break in WWD during New York Fashion Week, and in the March issues of American Vogue, Pop, Another Magazine, Vogue Italy, and W.
