Whew! Nick Jonas brought the steam in his sultry performance of "Chains" at the 2015 iHeartRadio Music Awards.

The singer literally donned chains while he sang his hit song. (It reminded us of "A Christmas Carol," but points for committing to the theme.) Of course, NJ's vocals were on point as he crooned, "You got me in chains, you got me in chains for your love /
But, I wouldn't change, no I wouldn't change this love." Sigh.

Spoiler alert: Just in time for the second verse, Nick was liberated from his chains. (He celebrated by hitting a crazy high falsetto. Approved.) Considering this song has been in constant replay pretty much everywhere since last fall, we're impressed that the singer still managed to make it sound fresh. The mark of a true professional, right?
