Ever since first seeing snippets of the actress in her latest venture for the French fashion house, we've been waiting to feast our eyes on the full ad - and it doesn't disappoint.

The 3-minute mini-movie sees the Brit actress reprising her role as the face of the Coco Mademoiselle fragrance, in guise as a seductive Chanel-clad biker chick.

The advert opens with Keira waking up to her bottle of perfume, before pulling on her chic Chanel catsuit and jumping on her matching motorbike. (Oh yes.)

The Brit beauty then rides through the streets of Paris to get to the luxury Chanel headquarters, where she's all set for a costume fitting and photoshoot.

But things soon start to get more than a little steamy with the photographer, as he finds himself transfixed by Miss Knightley.

Well, needless to say, that catsuit doesn't stay zipped up for very long...

We won't spoil the ending - you'll have to watch it for yourself to find out what happens!
