Katy Perry and Justin Trudeau spotted kissing on a yacht and confused fans 'can't get over' one bizarre detail

Katy Perry and Justin Trudeau seemed to have confirmed the romance rumours as photos have emerged of the unlikely pair kissing on a yacht.

For those who aren't up to speed, pictures were revealed yesterday (Sunday 12 October) of the 'Teenage Dream' hitmaker, 40, and former Canadian Prime Minister, 53, getting cosy at sea.

The photos, which were reportedly taken a few weeks back now on 29 September, were snapped by by tourists on a whale-spotting charter who hilariously got more than they bargained for.

Katy and Justin were seen embracing as they stood on the top deck of the vessel, seemingly sharing a smooch at one point.

It comes after they were spotted together for the first time in July, when they were together on what seemed to be a romantic dinner date, chowing down on lobster in Montreal as per TMZ.

Then, just one day later, Justin was spotted on 30 July, singing along to 'Firework' at Katy's concert in Montreal, Canada, as part of her Lifetimes Tour.

Up until now the idea of an actual romance between the pair has been simply speculation, however, it's looking a lot more realistic now - and fans are obsessed.

People have rushed to social media to talk about how well-suited the unexpected couple are, and the more eagle-eyed among them have picked up on one surprising detail.

Fans can't seem to get over the crime of fashion that is Justin Trudeau wearing skinny jeans on the yacht.

Yep, if you didn't notice it the first time, take a look again.

He really took "I'ma get your heart racing in my skin-tight jeans / Be your teenage dream tonight" to a new level.

The former Canadian PM decided to ditch the swimwear and bizarrely opted for jeans instead, while Katy is more appropriately donning a one-piece swimming costume.

Fans have hilariously reacted to the clothing choice on social media, with it getting almost as much attention at the romance reveal itself.

One Reddit user questioned "Why is he wearing jeans on a yacht?" while a second added: "I can't get past that he's wearing jeans in this lol"

"Couldn't avert my gaze from him in his jeans," admitted a third.

While a fourth penned: "Is he f**kin' wearing jeans on a yacht? As a Canadian, I'm embarrassed."

And other social media users penned: "He is Canadian so technically blue jeans count as swimwear" and "Why is he wearing long pants?!?"

"Why are you in pants Mr Prime Minister?" another fan jokingly asked, while someone else agreed: "Justin Trudeau is a psychopath, who wears jeans on a yacht?"

"Katy Perry and Justin Trudeau are a thing now. I have just one question: Why is he wearing jeans?" quipped someone else.

Meanwhile, others joked: "Lol at Justin Trudeau wearing jeans on a yacht" and "Unexpected duo! And yes, jeans on a yacht - bold choice."
