VIDEO: Watch Christina Aguilera's Team Perform 'Lady Marmalade' on 'The Voice' and Totally Crush It

Tuesday night marked the first live episode of "The Voice," as the vocal competition show expanded back to two hours and featured the finalized teams competing against each other.

It was Team Christina Aguilera versus Team Blake Shelton last night, and though performers on Team Blake did well (Dia Frampton performed a unique cover of Kanye West's "Heartless" that was quite lovely), their group performance paled in comparison to Team Christina's.

The four contestants and Xtina herself took the stage together to perform "Lady Marmalade" about halfway through the show, and just about brought the roof down. Afterward, all Carson Daly could say was "wow," partly because the crowd was going nuts.

If you haven't been watching "The Voice," here's a taste of what you're missing. Check out Team Christina's performance of "Lady Marmalade" below.
