Andy Samberg and Adam Levine perform 'Popstar' single on 'The Voice'

Humility is a dying virtue, but The Lonely Island promises to bring it back with the movie Popstar: Never Stop Never Stopping. In honor of the musical comedy trio's upcoming film, Andy Samberg and Jorma Taccone stopped by The Voice to perform one of the movie's songs live.

"I'm So Humble" features Adam Levine's hologram in the Popstar trailer -- but Tuesday's episode of The Voice had Levine performing with Samberg as Conner4Real live in 3D. Levine sings the chorus while Samberg raps lyrics that scream Lonely Island.

Bar none, I am the most humblest
Number one, at the top of the Humble List
My apple crumble is by far the most crumble-est
But I act like it tastes bad

The thing about me that's so impressive
Is how infrequently I mention all of my successes
I poo-poo when girls say that I should model;
My belly's full from all the pride I swallow

Before the song, Samberg spoke to Levine's team of singers in character as Conner4Real. Conner advised the team about fame and talent, and the contestants played along with the Popstar tone.

Popstar is a mockumentary about Conner4Real, a worldwide pop sensation who's "so ordinary it's extraordinary." The song lists Conner's accomplishments and all the laudable ways he somehow remains grounded.

Popstar hits theaters June 3.
