Justin Trudeau and Katy Perry Make It Official, Step Out Hand-In Hand In Paris

Katy Perry and Justin Trudeau went public with their romance on Saturday night as the lovebirds went on a date night in Paris, France to celebrate Katy's 41st birthday.

For their first official appearance, Katie and Justin attended a cabaret show at the Crazy Horse in Paris, where paparazzi were waiting for them at the entrance.

TMZ got exclusive video of what happened next… After the show, the couple walked out of the theater holding hands, with a fan giving Katy a rose and wishing her a happy birthday.

They then walked to a waiting car and photojournalists took photos of them before being driven away. Of course, Katie and Justin looked amazing together and seemed happier than a clam.

Earlier this month, TMZ published photos of the singer and the former Canadian prime minister cuddling on Katy's yacht and passionately kissing off the California coast.

In July, the couple first sparked romance rumors after they were seen out for dinner in Montreal followed by a walk in Mount Royal Park. Justin then appeared at one of Katy's concerts, also in Montreal, during her Lifetimes tour.
