Eva Longoria fearlessly hit the floor on this week's "Lip Sync Battle." The "Telenovela" star performed Flo Rida's club anthem "Low" while her rival, Hayden Panettiere, sang along to the side. While Longoria got the crowd going, the "Nashville" star certainly held her own as she channeled Christina Aguilera in a rendition of "Lady Marmalade" and revealed a secret weapon: Xtina herself. Fortunately for Longoria, she has another round to bring her A game.
