The sighting comes days after the "Pirates of the Caribbean" star applauded a satirical post trolling Perry's rumored romance with the former Canadian prime minister.

Katy Perry and former Canadian prime minister Justin Trudeau went viral for their three-stop Montreal outing—a park walk, followed by dinner, and then drinks—a week ago. Today, a source told Us Weekly that yes, they were “definitely on a date”—and that Trudeau and Perry had been in contact for weeks leading up to their rendezvous.
