No wonder I fall for Englishmen all the time. But not anymore." Aw! As Perezcious readers know, after her breakup from Orlando Bloom, Katy and Justin stepped out for a dinner date in July. Justin then attended one of her concerts. They seemed to really hit it off, but according to reports, they fizzled quickly because all the attention was too much for the 53-year-old politician. However, it turns out they never stopped seeing each other - they were just doing it in secret! But now that those yacht snapshots are out there, all eyes are on them! Hopefully, that doesn't cause any issues... Reactions, Perezcious readers? [Image via MEGA/WENN] The post Katy Perry Cheekily Hints At Justin Trudeau Romance During Concert!
