Sophie Grégoire Trudeau is navigating her ex-husband Justin Trudeau's public relationship with singer Katy Perry more than two years after their separation. In a recent interview with Canadian businesswoman Arlene Dickinson on the YouTube series "Arlene Is Alone: The Single Life," Grégoire Trudeau emphasized her ongoing partnership with Justin in raising their three children. "I’m definitely not a single mom. I have a partnership with a father who has such deep love and availability to his children," she stated. The conversation covered various topics, including mental health, motherhood, and the challenges of living in the public eye. Grégoire Trudeau acknowledged the emotional toll of public scrutiny, saying she has learned to "listen to the music, not the noise." Dickinson expressed her admiration for Grégoire Trudeau's composure amid the media attention surrounding Justin and Perry, referencing widely circulated images of the couple. "I don’t know how you stay cool ... I really admire it because I would probably not be that way," Dickinson remarked. In response, Grégoire Trudeau recognized that public life can be challenging. "Stuff affects us," she said, but she chooses not to remain in a reactive state. "How you react to stuff is your decision. The woman I want to become through this is my decision," she added. Grégoire Trudeau married Justin Trudeau, the 23rd Prime Minister of Canada, in 2005. The couple separated in 2023, but they have not publicly announced plans for divorce. They share three children: Xavier James, Ella-Grace Margaret, and Hadrien Gregoire. When asked about her experience as a single mother, Grégoire Trudeau clarified that she does not identify as one. She credited Justin for his commitment to their family, stating, "I can’t say I’m a single mom because we have raised these kids together." She also discussed the pressures of being part of a high-profile family, noting the constant scrutiny and the stress it places on her and her children. "You’re constantly reacting, knowing that when you go out there, the partner and the man you love, and your kids, they are under physical and psychological stress and safety issues. That’s hard to face as a family," she explained. Despite their separation, Grégoire Trudeau emphasized their shared commitment to co-parenting. "We have separate lives, but we have one family life, right?" she said. The interview did not touch on Grégoire Trudeau's new relationship with Ottawa pediatric surgeon Dr. Marcos Bettolli, which may have begun before her separation became public. However, she has previously expressed her pain over the end of her marriage, stating, "It hurts deeply. You know, marriage is ‘success.’ Separation and divorce is ‘failure.'" In this recent discussion, Grégoire Trudeau focused on personal growth. At 50, she reflected on the importance of self-care and making choices that affect her happiness. "At the end of any day, you must ask, ‘What did I do to take care of myself?’" she concluded.
