Shawn Mendes has been met with rave reviews after belting out his hit new song 'Wonder' on Jimmy Fallon.
The singer moves around a dully lit room as he passionately performs.
Shawn's new album is set for release on December 4 - and we can't wait. As one excited fan wrote on YouTube "life’s too short to pretend you don’t like Shawn Mendes" - frankly, we agree!
