Justin Trudeau is officially Katy Perry’s biggest fan! While in France, the former Canadian prime minister was spotted watching from the wings as Katy took on her now-iconic giant water bottle stunt during “I Kissed a Girl” - and even pitched in behind the scenes, helping hold a light during one of her photoshoots. We Canadians are just so nice eh? 😇 🇨🇦 📽️📸: #katyperry #justintrudeau #couplegoals
