Gorgeous British actress Keira Knightley is starring in a sexy new ad campaign for famed French fashion house Chanel shot in Paris the other day. Knightley, clad in a skintight, full-length bespoke beige leather bodysuit specially designed for her by Karl Lagerfeld, sat astride a classic 1970s Ducati Super Sport painted to match. She also wore a custom helmet from Les Ateliers Ruby, the French luxury brand which collaborated with Lagerfeld on a series of haute couture motorcycle helmets for Chanel a few seasons back. Of course, Knightley also sported a bespoke pair of riding boots and gloves to match, the whole a nod to Emma Peel of Avengers fame. The ad campaign was shot at Paris' famed Place de la Concorde, stopping traffic in the process.
