Christina Aguilera loves to change things up.

When the "Your Body" singer and her fellow mentors Adam Levine**, Blake Shelton** and Cee Lo Green** selected The Voice's final 12 contenders Nov. 8, the 31-year-old pared down her typically over-the-top styling.

Taking the advice of hairstylist Mark Townsend, Aguilera wore her platinum and strawberry blonde hair in a tight bun. "I wanted Christina's hair to be chic and beautiful to show off her gorgeous face," Townsend says on the five-time Grammy Award winner's official website.

Makeup artist Kristofer Buckle opted for a more dramatic approach. "I used black track gel liner by MAC to create a wicked sharp liner on her upper lid, then used black smokey eye shadow under her eye to complete the shape," he explains. "Then [I used] the same eye shadow in the crease with an iridescent white loose sparkle dust from LaFemme."

Buckle, who was inspired by Dorothy from the Wizard of Oz, used red glitter on top of Ruby Woo by MAC lipstick "to give [her lips] a ruby slipper look."

Aguilera's longtime stylist, Simone Harouche, says they both "fell in love" with a Peter Piloto pencil skirt "that fit her body like a glove."

From there, Harouche says, they added "a strong rock n' roll leather Versace belt and Louboutin shoes." The Burlesque actress also wore a sheer black top over a blue leopard bra. Aguilera completed her look with Roseark earrings and a white gold and diamond ring from Loree Rodkin.

Aguilera's team members Adrianna Lousie, Dez Duron and Sylvia Yacoub advanced to the final 12. The Voice airs Mondays and Tuesdays at 8 p.m. EST.

The singer's new album, Lotus, is in stores Nov. 13.
