What Happened: The Big Reveal of Justin Trudeau’s Halloween Costume
On Halloween night 2025, Justin Trudeau took to social media to unveil his creative costume, turning a simple father-son moment into a global talking point.
The 53-year-old posted a series of photos showing him in an inflatable blue shark suit, posing dramatically with a fake surfboard that looked like it had been chomped by, well, a shark. His youngest son, Hadrien, complemented the look perfectly as a terrified surfer, complete with fake blood dripping down his face and a wetsuit for authenticity.
Trudeau’s caption kept it light and heartfelt: “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.” He even included behind-the-scenes shots of them crafting the prop surfboard at home, adding that DIY charm that fans adore.
This wasn’t just any shark outfit. Observers immediately spotted the resemblance to the “Left Shark” meme, a cultural phenomenon from a decade ago. The post exploded online, garnering over 9,000 likes and hundreds of reposts within hours, as people connected the dots to Trudeau’s personal life.
The Father-Son Teamwork That Stole Hearts
What made Justin Trudeau’s Halloween costume even more endearing was the evident bond with his son. In one photo, Trudeau is seen at a table, meticulously cutting foam board for the surfboard prop. Another shows Hadrien painting it with red splatters for that gory effect.
This hands-on approach harkens back to Trudeau’s reputation as a devoted dad, even amid his high-profile life. Sharing these moments publicly adds a layer of relatability—after all, who hasn’t bonded over a craft project? It’s a reminder that behind the headlines, he’s navigating single parenthood post his 2023 separation from Sophie Grégoire Trudeau.
Fans praised the wholesome energy, with comments like “Pure dad goals!” flooding the post. This family-focused twist elevated the costume from mere fun to something emotionally resonant.
The Katy Perry Connection: Decoding the Left Shark Reference
At the heart of the buzz around Justin Trudeau’s Halloween costume is its clever tie-in to Katy Perry’s legendary 2015 Super Bowl XLIX halftime performance.
For those needing a refresher, Perry’s show was a spectacle of color and energy, featuring hits like “Roar” and “Firework.” But it was her backup dancers—dressed as sharks—that stole the spotlight. Specifically, the one on her left, dubbed “Left Shark,” went viral for its off-beat, freestyle dancing that contrasted with the choreographed precision of the right shark.
The meme exploded online, symbolizing joyful imperfection. Bryan Gaw, the dancer behind Left Shark, later reflected on the moment in a 2025 interview, calling it a “surreal” decade-later phenomenon.
Trudeau’s choice to specify “the shark (to his left)” in his caption? That’s no coincidence. It’s a direct nod to Perry’s viral shark, especially timely as their romance rumors heat up. Media outlets like TMZ dubbed it a “nod to his new boo,” while E! called it “fintastic.”
This tribute feels personal and playful, blending Perry’s pop legacy with Trudeau’s newfound freedom.
Why Left Shark Still Resonates in 2025
Ten years on, Left Shark remains a cultural icon. TikTok videos recreating the dance have surged in 2025, tying into Perry’s ongoing Lifetimes Tour. It’s a symbol of embracing flaws—something Trudeau, post his political ups and downs, might relate to.
