It was clear that Shawn Mendes does not need to do much to make girls weak in the knees when he hit the stage at the 2017 American Music Awards on Sunday night (November 19).

With his band in the background, Mendes was one to watch during his performance of "There's Nothing Holding Me Back." From the moment he started playing those guitar chords, the young ladies in the Microsoft Theater started screaming their hearts out. (Some were even in tears!)

There were no backup dancers, fireworks or special guests: It was just Shawn and his guitar, and that's all we needed.

Shawn is up a few American Music Awards including Favorite Adult Contemporary Artist. Best of luck to him!
