Watch Alessia Cara Crash Sabrina Carpenter's Interview (VIDEO)

 

At the iHeartRadio Music Festival, there's one thing you need to know: Always expect the unexpected. And you may see many of those great surprises on stage, but there are a lot of awesome moments that happen backstage too. Like crashing interviews -- which happened several times this year, one of them being Alessia Cara showing up during a live YouNow broadcast with Sabrina Carpenter.

Yup. It happened. Sabrina was backstage doing a live interview on YouNow and singing random comments from fans, which morphed into a riveting song called "Oy." Then, all of a sudden, Alessia crept up behind Sabrina and crashed the interview/broadcast/"Oy"-singing.

Alessia then joined the broadcast, and they both continued to sing comments that fans on YouNow were writing to them. We know ... FOMO.
