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

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 on March 21.

"Nobody said exactly what it was going to be like," she says in a voice over in the video teaser. "I knew that it was something about a motorbike, and I knew that it was going to be beige. They said, 'Sort of catsuit,' and I said, 'OK.' It was completely unexpected. It's a Chanel superwoman, I think."
