Is it 2001 all over again?

While watching The Voice last night, we couldn’t help but notice that Christina Aguilera’s outrageous — and revealing — ensemble (accessories included) was very reminiscent of her "Lady Marmalade" music video outfit.

But this time, it wasn’t Lil’ Kim, Mya and Pink joining her on stage for a live performance— it was Voice co-coach, Cee Lo Green.

On the Nov. 13 elimination episode, the pair performed their duet “Make the World Move” off Xtina’s new album Lotus.

In typical Xtina and Cee Lo fashion, the number was very exciting, but we couldn’t take our eyes off her racy wear!

Sporting a Moulin-Rouge like outfit, thigh-high white boots and a you-can’t-miss-it-if-you-tried frizzy pink wig, the 31-year-old songstress wowed the crowed with her pipes — and her get-up.

See last night’s performance below — and let us know: What do you think of Xtina’s attire?
