On Friday's episode of Hawaii Five-0, the American Idol Season 11 winner channels his villainous side as Voss, a diamond smuggler whose on the run from Five-0 after his partner is killed.

In ET's exclusive clip, it's clear that Voss will stop at nothing to get his hands on their last batch of contraband: a bag of expensive diamonds. Just when Voss thinks he's in the clear, the Five-0 team crashes the party, stopping him dead in his tracks. Watch the video above to see what happens next.

This isn't the first time Phillips has appeared on a scripted television series, however. He guest starred on CBS' Pure Genius in 2016 as himself, but Hawaii Five-0 marks his true acting debut portraying a fictional character.

The timing of Phillips' guest spot is pretty perfect. The 27-year-old singer-songwriter is set to release his third studio album, Collateral, featuring singles "Miles" and "Magnetic," on Friday, before going on a U.S. tour from Feb. 9 through April 14.

Hawaii Five-0 airs Fridays at 9 p.m. ET/PT on CBS.
