Every season there are hundreds of "exclusive backstage" videos, giving you a sneaky glance into the world of the makeup artists, stylists, and models at London Fashion Week - this one beats them all hands down.

Just when we thought we couldn't love them any more than we already do, gorgeous girls Rosie Tapner, Jourdan Dunn and model of the moment Cara Delevingne (who all walked for Topshop yesterday afternoon with model cams attached) took 3 minutes of out their hectic LFW schedules to jump on the Harlem Shake craze before the Topshop Unique AW13 show. Watch the video below - we dare you not to giggle. Who knew viral dancing could be done with so much style?
