Guess Who This Sweet Boy Turned Into!

Before this cool kid turned into an absolute star, was dropping #1 albums and was touring all across the world, he was just owning the hockey rink ... showing off his skating skills and teaching himself dance moves in Canada.

This guy definitely puts purpose behind every note he hits, and he definitely knows how to own the stage. When he's not in the recording studio, you can find him on his Instagram repping his clothing line ... always with a smiling face.

Need one more hint? He joined Ariana Grande on the Coachella stage back in 2019.
