Christina Aguilera has outdone herself again.

When Aguilera, 31, came out onstage during a live episode of NBC's "The Voice," she shocked viewers with her pink Afro wig accessorized with a tiara.

The petite singer wore the same pink Afro that was a part of her sexy Halloween costume, with an equally attention-getting outfit for her duet with Cee-Lo Greene. Her cleavage spilled out of her print strapless dress with a floor-sweeping train for the live show on Tuesday, Nov. 13.

The NBC mentor accented the look with star-spangled earrings, a black fur around her shoulders, and a white lace fan she held as she strutted around in her crystal-embellished thigh-high boots.

The "Voice" judges performed her song "Make The World Move" from her latest seventh studio album, "Lotus."

"About to #MakeTheWorldMove with @CeeLoGreen on @NBCTheVoice tonight. You better not miss it!!!" Aguilera tweeted before the show.

Last week, Aguilera was panned by critics when she displayed an odd hairstyle with patriotic jeans for a taped appearance on "Extra!".

Aguilera joined her "Voice" panel for a sitdown with host Mario Lopez at The Grove on Monday, Nov. 5, to promote the hit singing competition reality show.

The "Beautiful" singer stood out with a unique braided pink and bleach blonde hairstyle. Instead of sporting traditional cornrows or a simple French braid inspired by the latest fashion runway shows, the "Voice" mentor debuted a cornrow braid on one side of her head designed like a curled up snake with pink ombre tips.

In addition to the flashy hairstyle, the Staten Island native sported a zippered tee, leather vest and star spangled print jeans with excessive amounts of jewelry and spiked Christian Louboutin high heel shoes. The pop singer's patriotic pants might have been her take on Election Day, which was the day after.
