Chanel has replaced Kate Moss in its ads for its Coco Mademoiselle fragrance with Pride & Prejudice star Keira Knightley.

The 21-year-old actress will appear as the new face of Chanel starting next year, the company announced. (This summer she will appear with Johnny Depp and Orlando Bloom in Pirates of the Caribbean 2: Dead Man's Chest).

Moss's contract expired last October, ending the 32-year-old British supermodel's role with Coco Mademoiselle that had begun in 2002. Last year, Moss lost several high-profile modeling contracts – including those with Burberry and H&M – after a London tabloid published pictures of her allegedly using cocaine in a music studio.

Other previous faces of Chanel have included French star Catherine Deneuve and Nicole Kidman, who represented Chanel No. 5.

"Keira Knightley is a bright, young actress who has already made her mark in a diverse portfolio of films, including her Oscar-nominated performance in Pride & Prejudice, said Chanel artistic director Jacques Helleu in a statement.

Knightley said in a statement that she's "really proud to have been asked to work with such an iconic house as Chanel, and thrilled to follow the extraordinary women who have been associated with it before."
