Former Canadian PM Justin Trudeau in Katy Perry video

Former Canadian Prime Minister Justin Trudeau made a surprise cameo in a social media video posted by his girlfriend, pop star Katy Perry, sparking widespread online reaction. The clip, which Perry shared on July 9, shows the former leader hopping playfully in the background as Perry and her crew dance to her new single, "Watch It Burn."

The video was filmed in a bus lot, reportedly in Stuttgart, Germany, where Perry is currently on her European tour. In the brief clip, Trudeau, 54, bounds into the frame, looks at Perry, 41, and hops away after a few seconds. Perry captioned the post, "Ancient texts say that if you hop to this song you will get 1,000 years of good luck." The post has garnered millions of views and thousands of comments.

Online reaction was sharply divided. Many users mocked the former G7 leader's appearance, with some describing him as hopping like a rabbit or comparing his role to that of a background dancer. Others defended Trudeau, calling the moment sweet and a sign of a supportive partner. Supporters, including many Canadians commenting on the post, expressed happiness at seeing the former prime minister appearing genuinely content.
