Keira Knightley sings her way through Chanel's new Coco Crush video

Keira Knightley has carved out a stellar reputation as an actress, but the British star has now proven that she can sing beautifully, too -- in French.

The actress shows off her vocal skills in the new campaign video for Chanel's Coco Crush jewelry line, in which she sings the classic French song "Le Tourbillon de la Vie." Accompanying herself on a Chanel guitar that she removes from a signature quilted leather case, the star showcases multiple chunky rings and bangles from the luxury Coco Crush collection.

The song, which featured in the 1962 film "Jules et Jim," has previously been covered by fellow Chanel ambassador Vanessa Paradis.

Knightley was first unveiled as the face of the Coco Crush line in June 2016, when she was photographed by Mario Testino for that year's fall campaign. She was already affiliated with the fashion and beauty house, having been the face of both its ‘Coco Mademoiselle; fragrance and its signature lipstick ‘Rouge Coco.'

The Coco Crush collection was first unveiled in April 2015 as a tribute to Chanel's signature quilted motif, focusing on rings and cuffs in white, yellow and beige gold. Last September, the brand announced plans to expand the collection, by adding new pieces partially paved with diamond constellations.
