Billboard Music Awards co-hosts (and new best friends) Ludacris and Chrissy Teigen sat down during their recent Billboard cover shoot to talk about an apparently controversial topic: participating in Lip Sync Battle.

"Rappers don't lip sync," Luda said defiantly when Teigen asked him if he would consider appearing on the Spike TV show she co-hosts with LL Cool J. After she pointed out all the rappers who had already hit the stage on the surprise hit show (Salt-N-Pepa, Common), he amended his earlier statement: "You will not see me lip syncing -- it's just something I don't do." It's not all said and done yet though -- Teigen added, "I'm gonna have LL call you."
