Twilight's Ashley Greene made a noteworthy attempt at a half-up style but we had to give top honors to Madge's classic bouffant. All you need: a blow-dryer and round brush, lots of back-combing and a really good hairspray from L'Oreal.

Katy never fails to be the poster girl for "pretty" with her trademark vintage-inspired makeup and hair. We loved the silver eye shadow (try Urban Decay's Vapor), which both brightened up her whole face and matched her eventual lip color change from pink to red.

It's no surprise that this Victoria's Secret model wowed us with her natural makeup and gorgeous sun-kissed waves. To get her seemingly effortless look, try VS's "secret" cocktail of mousse throughout damp locks and volumizing spray at the crown, followed by a head full of pin curls.

For yet another year, Pink grabbed our attention with her hair. While her "windswept" pixie's unreal height made us think of a cockatoo (and almost landed in "worst" territory), its cool color and piece-y texture won us over, especially after seeing all the other short styles that night.

Leighton's daring look could've been a hit had she opted for either the messy half-up hair or the dramatic eye, but both? Much too heavy for such a natural beauty.
