Niall Horan and Shawn Mendes have performed an amazing duet together.

Their performance comes after Shawn previously admitted that he had chatted to the Mullingar man about working and writing together.

Now fans have been treated to what they can expect from the two, as the pair broke out in song together backstage at the American Music Awards.

Performing Shawn’s song Mercy, Niall sang along with the Canadian as he strummed a guitar.

The pair have become close pals in recent months, as they even hung out together after the awards bash.

At the awards, Niall performed his debut solo single This Town, while Shawn belted out his hit songs Treat You Better, as well as Mercy.

Niall even shared a snap of the pair on his Instagram, relaxing after the event.
