Keira Knightley's latest role? Biker chick.

But there will be no painted-on stone-washed jeans, fringed leather bras, or bandannas for this gal.

This is Chanel, after all.

Knightley shot an upcoming campaign in Paris for the luxury fashion house's Coco Mademoiselle fragrance -- filmed by her "Pride and Prejudice" and "Atonement" director Joe Wright -- while wearing a camel-hued biking outfit complete with matching helmet and motorcycle.

Fancy!

So is Chanel returning to its waify roots after featuring plus-size model Crystal Renn in its Fall 2010 campaign? Who cares -- we've got a double-C logo chopper to find!
