Justin Trudeau Helps Katy Perry Promote ‘Watch it Burn’ Single With Goofy TikTok Dance: Watch

Most pop stars don’t get politicians endorsing their songs, but Katy Perry isn’t like the others. The hitmaker promoted her new single “Watch It Burn” in a recent TikTok, which featured former Canadian prime minister Justin Trudeau — who just so happens to be Perry’s boyfriend — giving his seal of approval by letting loose to the track.

The clip posted on Thursday (July 9) opens with the musician outdoors in a bus lot, singing the lyrics to her June-released song in close-up. Then, as the beat drops, she starts hopping up and down, moving backward a few feet to reveal a group of people bouncing around as well. After a few seconds, Trudeau joins in, bounding into frame and looking at Perry adoringly before hopping away, his hair flopping up and down.

“ancient texts say that if you hop to this song you will get 1,000 years of good luck,” Perry captioned the clip.

Trudeau would likely argue that his appearance in the video was another instance of “supportive boyfriend duties” calling. He previously used the phrase to explain why he’d skipped Canada’s opening World Cup match against Bosnia and Herzegovina in June to cheer on Perry’s performance at the United States vs. Paraguay face-off instead.

“Sometimes supportive boyfriend duties call,” he wrote on X at the time. “But you know who I’m rooting for to take the Cup.”

Perry and Trudeau have been dating since last summer, getting together after the singer’s split from longtime partner Orlando Bloom, with whom she shares a young daughter. In June, she and the politician made their red carpet debut at her Lifetimes Tour concert film premiere.

During a Q&A at the screening, Perry was open about her feelings for Trudeau, whom she called “the love of my life.”

“I fly super high,” she’d added at the time. “Sometimes I need to be anchored. To have that anchor finally makes me feel really whole.”

“Watch It Burn” dropped on June 25, debuting at No. 38 on Billboard‘s Adult Pop Airplay chart. Perry has 36 entries on the Billboard Hot 100 to date, including nine No. 1s.
