Model Arizona Muse, who we met in September at the Marc Jacobs show and later featured in "Meet the New Girl," has landed the spring 2011 Yves Saint Laurent campaign. She replaces Daria Werbowy in the label's new ads, which were shot by Inez van Lamsweerde and Vinoodh Matadin and show Muse posing against a lush, spiky-looking plant in the gardens of a Moroccan villa. The setting is meant to tie in with a forthcoming exhibit on Yves Saint Laurent's Marrakech-inspired designs.
