The top 10 stars who gave us major hair envy at the Billboard Music Awards

Mila Kunis upped the beauty stakes as she took the top knot from day to night, wearing her hair up in a slightly undone style for ultimate laidback glamour.

If you're looking for an edgy way to style your short hair, take note from Rihanna and add heaps of texture and volume, and if you have a fringe, keep it slightly tousled too for extra wow factor.

Ciara mastered the laidback chic look which saw her wearing her hair worn up in a loose bun, the front sections worn down in a poker straight style. Recreate her look easily by tying your hair into a ponytail, but instead of pulling all of the hair through, leave it halfway.

Kelly Rowland rocked the slicked back hair trend. Take a leaf out of the star's book and add heaps of volume at the roots to get her edgy look – you can also add a spritz of shine spray to recreate the glossy finish.

Jessica Alba showed off her gothic side with her dramatic smokey eye make-up, but we're also huge fans of the super sleek top knot hairstyle she chose, leaving the ends of her hair in a poker straight finish.

Zendaya had us reaching for the straighteners when she stepped out with this poker straight hairstyle.

Britney Spears looked every inch a beauty icon, leaving her blonde hair worn down in cascading tousled waves.

Demi Lovato gave us spring hair inspiration with her short bob worn down in a sleek style, swept into a side parting for instant red carpet glamour.

Ariana Grande turned heads with her trademark high ponytail style, keeping the look super sleek to show off her long dark chocolate tresses.

Idina Menzel left her dark brown tresses down in a sleek and smooth style with a middle parting, tucking them behind her ears to show off her dazzling statement jewellery.
