Will the real Christina Aguilera please stand up? Hayden Panettiere wears huge blonde wig and low-cut corset to perform Lady Marmalade on Lip Sync Battle... and the singer joins in the fun too

Season two of Spike's Lip Sync Battle got off to a bang with Beyonce joining Channing Tatum for a surprise collaboration on her song Run the World (Girls).

And the latest commercial shows the popular series has more surprises in store, as Christina Aguilera joins Hayden Panettiere onstage during her face-off with Eva Longoria.

The 26-year-old can be seen decked out in bling and red lingerie while performing to 2001's Lady Marmalade, as the hitmaker appears onstage from behind a wall of feathers.

For the performance Hayden has long, teased out blonde tresses, accessorized with a lavish, silver tiara placed atop her head.

The Nashville star can also be seen sporting a bejeweled, bright red bustier with a plunging front that showcases her ample assets.

She has accessorized the look with a large, silver diamond necklace, and is sporting long, red satin gloves.

To really mimic Christina's daring look from the 2001 Lady Marmalade video, Hayden also wears black booty shorts, fishnet tights, and thigh-high, red heeled boots.

Hayden also sports dark eye shadow, blush, and a cherry red lipstick for the over-the-top performance.

In the middle of the Heroes alum's performance, backup dancers arrive behind her holding up a wall of pink feathers, from which Christina Aguilera herself then emerges.

Co-host Chrissy Teigen and Hayden's competitor Eva Longoria go wild in the commercial as they see the songstress make her grand entrance.

Lady Marmalade was originally released in 1974 by Labelle, before it was cemented in pop culture history in 2001 when Christina, Lil' Kim, Mya, and Pink teamed up to record a cover of it for the Moulin Rouge! soundtrack.
