The Celebrity Smackdown Is On in Lip Sync Battle's Insane Season 2 Trailer

We didn't think it was possible, but it looks like Season 2 of Lip Sync Battle will be even better than the first, and the celebs are taking the competition to a whole new level.

After some healthy smack talk from Hayden Panettiere, Kaley Cuoco, Kevin Hart and Olivia Munn, we get a peek at the many extravagant numbers on tap for this round of competition. Take a look at the video below to see the Backstreet Boys accompany Gigi Hadid, Christina Aguilera lip syncing "Lady Marmalade," Shaq's Flashdance makeover and the spousal showdown between Channing and Jenna Dewan Tatum (which, could feature a surprise appearance from Beyonce...)!
