Praise! Christina Aguilera revisits 'Lady Marmalade' on 'Lip Sync Battle'

Lip Sync Battle officially has its second-best cameo.

Nothing will ever top Beyoncé joining Channing Tatum onstage for a rendition of Run the World, we are all very aware. But Xtina returning to Lady Marmalade complete with big hair, ruffles and a dolled-up Hayden Panettiere? Yeah, that's definitely got the No. 2 spot.

Watch the sneak peek of Thursday's episode below, and try not to break out into the dance you definitely choreographed to this song when you were in middle school.

The only thing better would be if Lil' Kim, Mya and Pink came out, too (maybe they're saving that for Thursday? One can dream.)

And since it's officially stuck in our heads, here is the glorious original video from way, way back in 2001.
