Justin Trudeau Joins Katy Perry’s TikTok to Promote “Watch It Burn”

On July 9, 2026, pop star Katy Perry released a TikTok video to promote her new single “Watch It Burn.” The clip, filmed in a bus-lot backstage area, shows Perry lip-syncing and hopping to the track before former Canadian prime minister Justin Trudeau bursts into frame, dancing alongside her. The unexpected appearance of the ex-premier, now dressed in a green T-shirt, quickly amassed millions of views and dominated entertainment feeds.

Perry and Trudeau began dating in the summer of 2025, after Perry’s split from Orlando Bloom. Their first public outing was a dinner date reported in July 2025. Over the following year the couple made several joint appearances, including a red-carpet debut at the Tribeca Film Festival in June 2026, where Perry referred to Trudeau as “the love of my life.” The TikTok dance marks the latest public display of their partnership, occurring more than a year after they were first spotted together.

Perry framed the TikTok as part of a broader promotional push for “Watch It Burn,” noting that the song debuted on June 25 and entered Billboard’s Adult Pop Airplay chart at No. 38. In a Tribeca interview she described Trudeau as an “anchor” that balances her life. Trudeau, meanwhile, posted on X that his participation was an example of “supportive boyfriend duties,” echoing language he used earlier in June when he missed Canada’s World Cup opening match to cheer for Perry’s performance at a United States-vs-Paraguay game.

The collaboration blurs the line between political figure and pop-culture icon, illustrating how former leaders can leverage personal relationships for media visibility. Trudeau’s willingness to appear in a commercial-style music promotion may influence public perceptions of his post-political brand, while Perry’s use of a high-profile partner amplifies the viral reach of her single. Both parties benefit from heightened exposure, underscoring the growing interplay between celebrity romance and entertainment marketing.
