Cuckoo for Keira as Coco.
Always-flawless Keira Knightley slips into a sexy suede Chanel catsuit -- and mounts a motorcycle -- in an upcoming new mini-film for Chanel's Coco Mademoiselle.
Helmed by acclaimed director Joe Wright (Atonement), the clip put the Oscar-nominated actress, who turns 26 this month, in Paris' famed Place Vendome.
"Nobody said exactly what it was going to be like," Knightley says in this behind-the-scenes video, exclusive to UsMagazine.com. "It was completely unexpected."
The full film -- part of a new print, web and TV campaign -- debuts later this month.
Watch Knightley become a "superwoman" in this sexy clip now -- plus, pick up the next issue of Us Weekly, on stands March 16, for more exclusive behind-the-scenes pics from the campaign!
