We love a good celebrity/brand collaboration, especially when it involves one of our favorite style icons. Kate Moss has debuted her second collection for Longchamp in a new series of ads shot for her Fall 2010 line. We're loving the patchwork top-handle bag Moss is carrying above—the multitude of textures and colors is appealing both visually and in a tactile way. Want to see the whole collection? Longchamp.com already has the purses available for your viewing pleasure (but you won't be able to purchase them until the fall). Plus, we got our hands on exclusive behind-the-scenes photos of Moss in all of her modeling glory. Click through our gallery to see the rest of Moss's work and other ads.
