"[I promised my mother I would behave] and I did!"Diane arrived in the French fashion capital aged 15.Within three years she had been singled out by Karl Lagerfeld as a Chanel muse.She remains fiercely loyal to the fashion house ever since."It was huge to be financially independent, and I loved the travel," Diane explained.Diane started to secure more and more modelling work.She was able to move to New York as a result, where she worked for Dior and Vuitton, before pursuing a career as an actress.
