Katy Perry and former Canadian prime minister Justin Trudeau are Instagram official. "Tokyo times on tour and more," Perry, 41, wrote via Instagram on Saturday, December 6, sharing a slew of photos in Japan. In one photo, Trudeau, 53, snapped a selfie with Perry as they took in the fall foliage. A second clip, meanwhile, featured the pair on a dinner date. "My first Uni," Perry said, trying a piece of sushi while Trudeau lovingly looked on with a smile.
