The two women recently squared off for Spike TV's insanely popular "Lip Sync Battle" and from the looks of it, viewers are in for a real treat with these two women on the stage.
The network released a sneak peek of Eva getting down and breaking out her best moves to Flo Rida's "Low."
The show will air Feb. 11.
For her performance, Eva rocks a backwards baseball hat, a black shirt, a black jacket and black pants... Oh, and boots with the fur, naturally.
Another sneak peek and images show Hayden dressed in her best burlesque outfit singing Christina Aguilera's hit "Lady Marmalade," and guess who makes a surprise appearance, Christina herself.
The two, of course, worked together last year on "Nashville."
"Lip Sync Battle" has featured some of entertainment's biggest names since it aired, including Channing Tatum going head-to-head with his wife, Jena Dewan-Tatum, Tim Tebow vs. Nina Dobrev and Kaley Cuoco vs. Josh Gad.
The winner of all the battles, including Eva and Hayden, get the ultimate prize: Bragging rights.
