Last weekend, Shawn Mendes was at our iHeartFestival in Las Vegas where he got to perform on stage with Justin TImberlake! And as you might know, Jimmy Fallon and Justin Timberlake are BFFs too. So Jimmy wanted to see how JT likes more - him or Shawn. Typical BFF stuff right?!
Shawn also performed Lost In Japan and of course played a game with Jimmy Fallon called Slay It, Don't Spray It which is pretty much what it sounds like!
