We're not talking tiny topknots or elegant ballerina buns - we're talking about huge buns!
Keep your style simple yet glam with this on-trend 'do.
How to get the celeb look...
1. Tie hair into a tight ponytail and pull hair through a doughnut ring (Boots, £4.69).
2. Spread hair evenly around the doughnut and hold in place with a clip (Superdrug, £1.79) until the ring's completely covered with hair.
