Does it feel like 2001 all over again, or is that just us?

In a preview clip released Monday teasing Thursday's episode of "Lip Sync Battle," Hayden Panettiere is shown channeling Christina Aguilera in the 2001 burlesque-themed music video for "Lady Marmalade."

Aguilera famously remade the iconic tune with Pink, Lil' Kim, Mya and Missy Elliott for "Moulin Rouge," the film that scored Nicole Kidman an Oscar.

Panettiere seems to have nailed X-tina's iconic "Marmalade" look and sexy, thrust-filled dance moves in her "Lip Sync" performance in which she's up against "Telenovela" star Eva Longoria. There's no indication of what song Longoria performs -- besides her '80s-style get-up -- but it Panettiere's true competition comes from Aguilera who makes a surprise appearance on stage with her.

Belting it out in her usual over-the-top Aguilera style, the "Voice" coach is wearing a black jacket and pants on top of a silver sparkling bra. In hand? Her signature red mic, of course.
