While The Voice focuses on the contestants' talents, and not their appearance (hence, the blind auditions), that’s definitely not the case for the judges, particularly Christina Aguilera.

Between her daring plunging necklines, sparkly gold eyeshadow and platinum blonde mane, the 31-year-old singer constantly steals the spotlight from co-stars Adam Levine, Blake Shelton, and even Cee-Lo Green.

And recently, everyone's been buzzing about the black disc-shaped crystal-studded headpiece she debuted during the first battle round episode.

Host Carson Daly gave the quirky accessory -- which is actually a headband designed by Sonia Rykiel -- a shout-out in his blog:

"Another thing I want to mention that America will be thrilled about in the battle rounds is… new wardrobe for all the coaches! What Purrfect the Cat was for conversation during the blind auditions, Christina Aguilera’s compact-disc hat will be for the battle rounds."
