When Cara Delevingne found herself in that situation recently, she did what any young supermodel with the world at her feet would do... Make bunny ears and gurn at him behind his back.
Thats the story of a super-cute short teaser video advertising Plastic Dreams: the in-house magazine of Melissa, with whom Lagerfeld has collaborated on a line of shoes. It not only features 16 exclusive shots of Cara modelling the designs (as unconventionally as ever - see above), but also an interview with the man himself.
It will be free to pick up from the Melissa boutique on London's South Molten Street and downloadable on iPhone and Android shortly.
In the meantime...
