Shawn Mendes decided to turn 19 in style, and celebrated his birthday with a wild poolside bash at a rooftop bar in Toronto.
The mild-mannered Canadian pop prodigy showed a different side of himself as he channeled his fellow Canadian sensation Justin Bieber’s fun-seeking ways.

Girls tried to get close to him and one even pawed at his face as he started dancing. At one point, he danced to a remix of There’s Nothing Holdin’ Me Back while the whole room sang along to the lyrics.

However, some ungrateful attendees asked him for a pic, then trashed him on Twitter.
