Keira Knightley revvs up for Chanel in the video teaser for the Coco Mademoiselle fragrance.

Rocking a nude catsuit and helmet, the 25-year-old English actress and model climbs onto a Ducati motorcycle in the fragrance's latest ad campaign. The sexy superwoman accentuates her badass ensemble with a loose wavy bob, bold brows, smoky eye makeup and rosy lips.

Knightley teamed up with her 'Pride & Prejudice' director, Joe Wright, last September for the short film that will debut March 21.
