Pentatonix fans better get ready to pick sides.

On this week's episode of Lip Sync Battle, four members of the a capella supergroup go head-to-head on the Paramount Network competition series.

Out Pentatonix member Scott Hoying goes up against fellow bandmate Kevin Olusola, while Kirstin Maldonado battles it out against Mitch Grassi.

In a new clip from the episode, Hoying reveals his inner dangerous woman as he recreates Ariana Grande's "Side to Side" music video, complete with spinning, short shorts and—if you look closely—naked men showering in the background.

"I was so hyper-focused on you that I barely noticed the naked men in the shower," co-host Chrissy Tiegen tells Hoying after his performance. Maybe you didn't notice, Tiegen.

Pentatonix are about to embark on a huge North American tour this summer in support of their new album, PTX Presents: Top Pop Vol. 1, featuring new covers of hit songs like "Havana" by Camila Cabello.

In addition to Pentatonix, Hoying and Grassi have kept busy with their side project, Superfruit, which has amassed its own rabid following, with their music videos racking up more than 350 million views on YouTube.

Lip Sync Battle airs Thursdays at 10/9c on Paramount Network.
