We’ve already rejoiced over how fabulous Rooney Mara looks in the new Calvin Klein ad, shot in New York by world-renowned director David Fincher. Mostly because it is a delight to see the softer side of Mara, a far cry from the harsh persona she displayed in The Girl With A Dragon Tattoo.

But hot off the press is something to trump that vid – no really, a game-changer to say the least. It's an exclusive, behind-the-scenes video, people. Yes, you won't have seen this anywhere and you're going to bloody love it.

It’s epic. Really. There’s nothing better than snooping backstage to see what really went on on a shoot and, well, voila, here you go. The puppy dog bit is still the best, as well as that hand twirling/dance-y thing she does straight after. Watch closely; we defy you not to girl-crush even more.

Oh and about the fragrance, it's a feminine, woody number that's modern and fresh with soft floral notes in the base too. Definitely worth waiting for, ladies.

Calvin Klein Downtown, £34, is on counter from 21 August.
