Justin Bieber and Shawn Mendes opened the 2020 American Music Awards on Sunday with the world premiere performance of their new song, among other jams.

Bieber got things started with the same super sad songs he’s been performing on TV for the past few weeks (“Lonely” and “Holy”) before being joined by a long-locked Mendes for the TV debut of “Monster.”

Watch footage of the performance below, which we’ll update with official video if/when it becomes available:
