In the newest clip for Lip Sync Battle on Spike— that hugely popular show in which you get to watch your favorite celebs make total fools of themselves as they compete to become lip-syncing champions—Will Arnett does some impressive Mr. Roboto moves in a construction worker suit as he competes against Alison Brie showing off some serious rapping skills.

Empire stars Taraji Penda Henson and Terrence Howard also go head to head, and while Henson may be bringing Mary J. Blige (literally and figuratively), Howard's epic wig and side-split during The Commodore's "She's a Brick House" promises to steal the show.

You can catch the new episode, which also features Iggy Azalea and her fiancé Nick Young, on July 9 at 10 p.m. EST on Spike.
