It's a Shondaland square-off on the next Lip Sync Battleand at least one competitor has come to the battlefield prepared for serious war.

In a preview of the Spike competition series' next episode, How To Get Away With Murder's Matt McGorry — who's no stranger to lip sync routines (just check out his Instagram for damning proof) — leaves it all on the floor. In the clip, McGorry immediately gets into character to exact Peaches & Herb's 1978 hit "Shake Your Groove Thing," and gyrates, struts and shimmies like Soul Train's calling.

"Dreams really do come true," McGorry captioned in an Instagram photo-preview of the face-off. "Some of the most fun I've ever had in a single day. And [Young] KILLS it!"

Young, meanwhile, tried her hand at Lady Gaga's "Born This Way" in a preview released earlier this week. It's a little bit glitzier, showier and spilling over with metallics, but will it be enough to beat out McGorry and take the top spot?

Check out the clips and see who comes out on top May 11 at 10 PM EST on Spike.
