Former Canadian Prime Minister Justin Trudeau has responded to online criticism after attending the United States' opening match of the 2026 FIFA World Cup to support girlfriend Katy Perry, while missing Canada's first game of the tournament on the same day. The debate began after Trudeau shared a humorous post on X, reacting to media reports that highlighted his decision to attend the US opener instead of Canada's World Cup debut. Addressing the backlash, Trudeau wrote, "Sometimes supportive boyfriend duties call. But you know who I'm rooting for to take the Cup," adding a Canadian flag emoji to underline his support for the national team. His remarks quickly sparked discussion across social media, with opinions divided. Critics argued that a former Canadian leader should have chosen to attend his country's opening match, with some suggesting the decision sent the wrong message. "Leadership is about putting the country ahead of personal relationships," one user commented, while others called the move disappointing. However, many social media users came to Trudeau's defense, saying he had every right to support his partner and criticizing what they viewed as an overreaction to a personal decision. "You literally owe no explanation to anyone. Live your life," one supporter wrote. Another added, "You served the country and deserve to enjoy your life without being judged for every personal choice." The controversy followed Trudeau's appearance at the FIFA World Cup opening ceremony at SoFi Stadium on June 12, where Perry headlined the pre-match entertainment ahead of the United States-Paraguay clash. During the performance, she sang her track "Wonder" alongside young Norwegian singer Tius Luka. Trudeau was spotted watching from the sidelines and later embracing Perry after her performance. The couple also shared a public kiss and were seen holding hands in the stands, moments that quickly went viral online. Perry dazzled at the ceremony in a futuristic silver sequined gown by Stella McCartney. The couple, who first sparked romance rumours in 2025, have made several public appearances together over the past year. Earlier this month, Trudeau accompanied Perry to the premiere of her concert film, Katy Perry: The Lifetimes Tour - Live from Paris, at the Tribeca Festival in New York City. He has also been seen attending her concerts and joined her at Coachella 2026 earlier this year, where the pair watched a performance by Justin Bieber together.
