For the unversed, Mark Carney took Office as the 24th Canadian Prime Minister earlier this year (in March 2025), replacing Trudeau."There's no way y'all don't know Trudeau isn't the PM anymore." - commented an X user."Seeing him at Katy Perry’s concert in Montreal is unexpected but kind of refreshing. It’s not every day a head of state steps out to enjoy a mainstream pop show but it’s nice to see someone in his position engage with culture not just diplomatically, but personally a reminder that even world leaders need a break from the intensity of political life" - added another."they should reboot Where's Waldo but do it with celeb pics like this" - wrote a third one.Meanwhile, other social media users mentioned "cheating" and "jumbo kiss cam" in the comments, drawing references from the viral Coldplay concert in Boston (held earlier this month), where Astronomer CEO Andy Byron's alleged affair with his HR head was revealed to the world."If someone isn't cheating then we don't want to hear about it" - posted a fourth netizen."Do they have the jumbo kiss cam in there ?" - questioned a fifth one."This is the weirdest publicity stunt of all time. 2020's are wild" - replied a sixth user."Trudeau looks VERY happy at the Katy Perry concert!" - commented a seventh netizen.Sources close to Justin Trudeau have shared the details about his relationship with Katy PerryA day before Trudeau was spotted at Katy Perry's concert, The Sun published an exclusive story on the ex-Prime Minister and Katy Perry.
