The Golden Globe winners go head-to-head in Spike TV's new Lip Sync Battle show, while dressed like Lionel Richie and M.C. Hammer.
Common proves he can pull off a Jerry curl as he performs Richie's 1983 hit "All Night Long." While his lip syncing skills could use some work, he should most certainly get some points for his sick break dancing moves.
Up next, it was Hammer Time! Legend attempts to one-up the rapper by performing M.C. Hammer's 1990 track "U Can't Touch This."
Which musician wins? Lip Sync Battle, hosted by L.L. Cool J, premieres April 2 on Spike TV.
"Once you're on this stage, you absolutely have to bring it and they do bring it," LL Cool J told ET. "It's the craziest variety show on the planet."
