French actress Marion Cotillard has signed on as a global ambassador for fashion house Christian Dior.

The La Vie en Rose star teamed up with celebrated photographer Peter Lindbergh for a saucy shoot at the Communist Party Headquarters in Paris to highlight the company's latest collection for bag line Lady Dior.

A recently-released advert features the Oscar winner wearing a plunging V-neck dress and seductively clutching a crocodile and raffia-textured purse.

The new ad campaign will make its debut next month.

Cotillard joins the ranks of Dior's long list of big name spokesmodels - actress Mila Kunis currently serves as the face of the brand's clothing range and Charlize Theron reps the firm's J'Adore perfume.
