Ex-PM Trudeau and Katy Perry Collaborate on Iconic Left Shark Halloween Costume

In a surprising turn of events, former Canadian Prime Minister Justin Trudeau appears to have found a new Halloween partner in pop star Katy Perry. On October 31, 2025, Trudeau took to Instagram to share a photo of himself and his youngest son Hadrien dressed up for the spooky holiday.

Trudeau, 53, revealed that he and Hadrien had built a costume together, with Hadrien dressed as a bloody surfer and Trudeau himself donning the iconic costume of Katy Perry's "Left Shark" from her 2015 Super Bowl halftime show performance. The former prime minister's shark costume was nearly identical to the viral moment when the "Left Shark" went rogue with its dance moves, stealing the show and becoming a cultural phenomenon.
