You've probably heard that Rooney Mara is the face of Calvin Klein's new fragrance Downtown, and if you'd taken any time to imagine what that might look like I would be prepared to bet you'd be bang on; the David Fincher-directed commercial has just been revealed and it is so perfectly suited to them both.

As with many a Calvin Klein advert, everything is in black and white, and throughout the monochrome Downtown land floats Rooney Mara, going from a leather jacket clad, subway riding cool kid, to a press conference giving, pampered model. Check it out above!

Oh and for those wondering that song is "Runaway" by the Yeah Yeah Yeahs.
