Justin Trudeau’s Halloween costume is a nod to new girlfriend Katy Perry

Justin Trudeau‘ gives a nod to his new boo Katya Perry with his Halloween costume… and he even got his son involved.

The former Canadian Prime Minister joined forces with his son for a joint costume this year… Justin wears a shark suit and his son Hadrine is a bloodied surfer whose board is missing a piece from a shark bite.

It’s a pretty cool father-son costume… even before you consider the reference to KP.

Remember, when Katy performed the Super Bowl halftime show in 2015, a pair of backup dancers behind her went viral… wearing similar shark costumes to Justin’s here.

Justin doesn’t mention Katy in his post about the costume, but simply says… “Getting ready for Halloween with Hadrien: he’s the surfer, I’m the shark (to his left). We built the costume together – a little father-son Halloween teamwork.”

But it’s pretty clear that Justin is giving a nod to Katy… he said he’s “on his left” and that the left shark was the one most people remember from her Super Bowl performance.
