Hayden Panettiere, Christina Aguilera Do 'Lady Marmalade' on Lip Sync Battle

It’s the Nashville reunion you didn’t even know was a Nashville reunion!

Hayden Pannetiere (aka Juliette Barnes) and Christiana Aguilera (aka Jade St. John) share the stage during Thursday’s Lip Sync Battle (Spike TV, 10/9c) for what appears to be a flawless recreation of “Lady Marmalade” from the Moulin Rouge soundtrack.

Though Aguilera is clearly the guest of honor — she’s the Beyoncé to Panettiere’s Channing Tatum, if you will — it looks like Panettiere has things pretty well under control, even without an assist from the song’s original belter. (To be honest, though, I would have also appreciated a visit from Mya. Where did she go?!)

TVLine has confirmed that the segment was taped before Oct. 13, when Panettiere checked into a hospital for treatment of postpartum depression — and thus took a hiatus from her ABC drama.
