The Toronto Maple Leafs gained a massive chunk of momentum by winning Game 5 against the Boston Bruins on Friday night, and pop star Justin Bieber let the public know where his sports allegiance lay in case there was any doubt.

The product of Stratford, Ontario, took to Instagram prior to the Leafs' 2-1 win over the Bruins to give them a leg up with a 3-2 series lead in the best-of-seven.

There's no Drake curse there.

While most megastars chose to ignore trolls who comment on their pages, Bieber opted to fire back at one poster who spammed the comments section by saying "go jets" three times.

Guess we know who Bieber would rather have between Auston Matthews and Patrik Laine.

The Jets official account got in on the action asking "Justin... I thought we were friends?"

But the top comment belonged to the Maple Leafs, who stayed away from the warzone below and simply put "looking good."

Bieber was spotted in a box seat with his wife, Hailey Baldwin, earlier this season, so don't be surprised if we see the Biebs back at Scotia Bank Arena  for Game 6 or if the Leafs advance to the second round.

From playing drop-in hockey, to challenging Shawn Mendes to a game of shinny, there's no denying Bieber's love for the sport and his favourite team.
