Katy Perry and Justin Trudeau are each other's lights at the end of the tunnel! As we've been following, the pop star and the former Canadian Prime Minister have been absolutely head over heels for one another since sparking romance rumors over the summer. Despite initially wanting to keep their romance under wraps, they've slowly but surely warmed up to attention - and even went social media official last weekend! Katy shared a string of loved-up selfies on Instagram and Justin shared a pic of the pair with former Japanese Prime Minister Fumio Kishida and his wife Yuko Kishida on X (Twitter).
