Marion Cotillard
knows a thing or two about singing on film: The actress won an Oscar for her portrayal of French chanteuse Edith Piaf in "La Vie en Rose," and more recently Cotillard played a director's wife in the musical "Nine."

Now, the face of Dior is once again proving her vocal prowess. After chapter one of the Lady Dior Saga, where Marion plays Lady Noire, the French actress is back for another installment as Lady Rouge.

This time, the beauty is the star of a music video, directed by Jonas Akerlund, where she sings Franz Ferdinand's "Eyes on Mars" in a red silk dress, as well as skinny menswear suit and tie (looking like a cross between Robert Palmer and his guitar-wielding backup singer clones in the "Addicted to Love" video).

The Swedish director lends an artistic and romantic touch to the four minute video (above) -- going from a moody living room scene to a cool stage set seamlessly. It should come as no surprise, as Akerlund has videos for music icons such as Madonna, Metallica and U2 under his belt.

And though the video was supposed to make its worldwide debut on March 5 alongside the Dior Fall 2010 runway show at Paris Fashion Week, behold the powers of the Internet.

Dior isn't relying solely on Cotillard for its ads, this 17-year-old model landed the luxury label's Spring 2010 campaign.
