A few days ago, Spike TV teased the guest appearance of Christina Aguilera on Lip Sync Battle, as Hayden Panettiere’s special guest during “Lady Marmalade.” That tease was maddeningly short, but after the episode aired on Thursday night (Feb. 11), we now have the full clip at our disposal.

Following Eva Longoria’s inspired “Anaconda” take, Panettiere blew away the crowd with pancake makeup, Moulin Rouge dancers and large doses of sass. Xtina is unveiled at the 2:45 mark, and delivers some amazing vocal runs (even if they are, due to the show’s nature, pre-recorded).

Did Christina’s surprise appearance outshine Beyoncé’s amazing Lip Sync take next to Channing Tatum? You be the judge.
