Chanel fans, rev your engines.

Keira Knightley -- who has been the effortlessly elegant face of Chanel's Coco Mademoiselle fragrance for four years -- was just spotted in Paris filming the best-selling scent's newest ad campaign on Sunday, and her outfit has been the talk of the town ever since.

Dressed in a pale pink-cream motorcycle bodysuit with matching helmet and bike, the 25 year-old British actress looks one part fashionista and two parts girl power in her perfectly coordinated gear and getup that mimics the color of the fragrance bottle.

The makeup is just as detailed. Pretty flushed cheeks, smoldering eyes and a soft pink pout pop behind a shiny glass face mask -- because why wouldn't you sport a flawlessly painted face for your jet around Paris?

Filming was shot at Place de la Concorde, one of the biggest public squares in the city of lights, which features a dramatic center fountain and is just west of the Champs-Élysées, where we imagine our stylish heroine is en route to for some serious shopping and an afternoon treat of cafe au lait and macaroons.

We imagine she'll spritz on her favorite scent afterwards, which is a blend of mandarin, bergamot, ylang-ylang, morning rose, Indonesian patchouli and tonka bean, vanilla and musk that was created to appeal to the French luxury brand's younger clientele in 2001 -- yet continues to remain a top-seller today.

Chanel is still mum on when the ads are scheduled to run, but we look forward to watching the finished film, with a glass of wine and our favorite Coco-inspired lipstick at hand.
