She wrapped her arm behind her new boyfriend, who wore a grey suit and slacks to meet with the former prime minster and his wife, Yuko Kishida.

On Oct. 25, Trudeau and Perry made their first public appearance as a couple while leaving the Crazy Horse Paris. According to TMZ, the couple attended a cabaret show at the Parisian hotspot in celebration of the pop star’s 41st birthday. 

During an appearance on the “Arlene Is Alone” podcast, Sophie Grégoire – who split from Trudeau in 2023 after 18 years of marriage – opened up about how she manages to handle the outside “noise” and navigate her emotions as her ex moves on.

“We’re all human beings and stuff affects us,” she said. “How you react to stuff, is your decision. So I choose to try to listen to the music instead of the noise.”

“I’m very aware that a lot of public stuff out there can be triggers, we’re humans,” she continued. “What I do with it is my decision. The woman I want to become through this is my decision. Does it mean that I don’t have emotions? That I don’t cry, scream, laugh? No!”

Despite the split, Trudeau and Grégoire — who share three children: Xavier, 18, Ella-Grace, 16, and Hadrien, 11 — remain a united front when it comes to their family.

“We have separate lives, but we have one family life,” Grégoire said. “And I think that we need two individuals in a couple … to detangle.”
