Lip Sync Battle: Josh Peck does Bieber

Grandfathered may have been canceled last week, but that doesn’t mean star Josh Peck isn’t a total winner. What do we mean? Well, just watch the above sneak peek of him really going for it as he performs Justin Bieber’s “What Do You Mean” on Lip Sync Battle.

Peck (and his questionable booty shake) will face off against his former costar, singer Christina Milian, who is taking on Jennifer Lopez’s “Waiting for Tonight” video.

See some of Peck’s performance above and watch the full battle Thursday at 10 p.m. ET on Spike.
