Roll up, roll up! US X Factor judge Demi Lovato's hair is right on trend
Demi's already gone for a pink dip-dye to give her long blonde locks a bit of edge.
But at the North Carolina auditions on 9 July she upped the ante, styling her hair into summer's hottest look: the retro roll.
The teen star complemented her half up, half down rockabilly do with a leather biker jacket and punchy orange frock as she arrived in Greensboro to record the show.
Demi finished off the fierce look with retro winged eyeliner.
We can't wait to see what hairstyle she goes for next!
