Shawn Mendes And Niall Horan Have Done A Duet And We're In Tears

Shawn Mendes and Niall Horan have been teasing a duet for what feels like a lifetime, but today, our dream ~literally~ came true. 

We all know that Shawn and Niall performed at the 2016 American Music Awards (AMAs), but unbeknownst to us, the action didn't stop onstage. They collaborated backstage, singing Shawn Mendes' smash hit 'Mercy', and we honestly can't breathe.

Have mercy on us.
