If you were at the Katy Perry concert in Montreal on Wednesday, there's a chance you heard former Prime Minister Justin Trudeau Roar among the crowd. Several photos and videos of Trudeau, 53, showed him dancing and singing along to the pop star's hit songs at her The Lifetimes Tour. He had a fantastic view of Perry, 40, who was suspended in the air on top of a fluttering butterfly. This sighting comes days after the unlikely pair were seen having a dinner date at celebrity chef Danny Smiles' restaurant, Le Plateau's Le Violon. Both Trudeau and Perry have recently undergone public splits with their respective partners: Trudeau having separated from ex-wife Sophie Gregoire Trudeau in 2023, and Perry, confirming the end of her relationship with ex-fiancé Orlando Bloom earlier in July.
