Katy Perry dropped a subtle hint that she can take a joke about her budding romance with Justin Trudeau. The pop star, 40, recently left a "like" on an Instagram post from parody newspaper The Onion, which shared a story on Monday, October 20, referencing Perry's relationship with the former Canadian prime minister, 53. "Katy Perry Releases New Single About Superiority Of Canadian Manufacturing," read the faux headline.
