Well, look what we have here. Yet another huge, global model saying 'sod it' to the world and cutting her hair off. Right off. Indeed, last night it was the turn of Coco Rocha, who was bold enough to allow Allure magazine to live tweet the entire process.

We called it weeks ago, but now cutting your long hair off has become the most unlikely badge of honour among the modelling elite and the style set. First it was the posh girls - Sheherazade Goldsmith and Charlotte Casiraghi. Then they were quickly usurped by such fashion royalty as Margherita Missoni and Annabelle Dexter Jones. Bravo, we all thought.

Then, hot on their heels came the models. Edie Campbell breathed a new energy into her career with a dyed-black shag cut. Followed by the deliciously beautiful Constance Jablonski, with her Kelly McGillis meets Marilyn Monroe bed-hair bob.

It's not difficult to see the appeal. Chopping it all off is a symbol of non-conformity, an empowering act especially for a model who will have no doubt enraged her bookers who now have to explain to brands why they can't style her hair how they want to any longer. More than anything though, it's just so viscerally liberating - physically and psychologically. It's a tragic cliché I know, but there's so much truth in the old-saying 'new hair, new you.' Of her new choppy bob, Coco said, 'It's exactly what I wanted, to a T. I'm freaking out, but in a really, really good way!'

Now, let's watch her soar...
