In the forthcoming Lonely Island movie Popstar: Never Stop Never Stopping, Andy Samberg plays a Bieber-esque sensation named Conner4Real. And in an inspired bit of synergy, Samberg, in character, was a guest on last night’s episode of the absurdly popular NBC singing show The Voice. On the show, Samberg and Voice coach Adam Levine sang their collaboration “I’m So Humble,” as a weird and elaborate ’50s-diner production number. And even better: Samberg, in character as Conner4Real, gave advice to the contestants, something that involved mercilessly making fun of Levine. The Voice contestants all did pretty well at reading their prepared lines. Watch the performance and the comedy bit below.

Popstar hits theaters 6/3.
