We knew Alexa Chung and Poppy Delevingne were part of the same clique but we didn’t realise just how close they are.

Writing in The Edit, Delevingne speaks of her close bond with Chung, which began when they met at a model casting 10 years ago but was cemented during a moonlit skinny-dipping session in Cannes in 2011.

« It was spectacular, » writes Poppy of the moment. « At 4am, rummaging through bushes for our stray couture, I realized it wasn’t just another friendship. »

She also reveals their shared weakness for whisky (Chung fell asleep at a craps table in Las Vegas after drinking a little too much) and boys (« I’m boy-crazy and always will be, but Alexa is really boy-crazy »).

The accompanying shoot for Net-A-Porter’s The Edit sees the photogenic pair take a very stylish road trip, sporting an array of lust-worthy designs.

Delevingne also talks of Alexa’s ability to « bring a suitcase the size of a piece of calamari and yet each day she’ll wear something mouth-wateringly stylish. »

« I’m guaranteed to have a smile on my face when she’s around, » she adds. « I asked her what her favourite road-trip movie is and she read my mind: ‘We’re the female version of The Trip!’ The tagline to that film is: ‘Eat, drink and try not to kill each other’. I’d say that sums it up perfectly. »
