Pint-sized pop star Ariana Grande has had a busy week. She's popped out of a spaceship (casj) to perform at the MTV VMAs, released her new single Break Free and her second album My Everything, and taken part in a worldwide trending Twitter chat. But if you missed all that, there's one thing you can't miss and that's her prolific ponytail: glossy, crazily long and enviously swooshy.

We asked one long-haired ASOS-er (Nellie Eden, junior news and fashion writer) and one short-haired ASOS girl (Shannon Cross, international & campaign content editorial assistant) to show us how to rock an AG pony: Ariana for all!
