Katy Perry and Justin Trudeau pack on the PDA on her yacht

Katy Perry and Justin Trudeau were recently spotted making out on the singer’s lavish yacht, confirming their romantic involvement.

In photos published by the Daily Mail on Saturday, the “Firework” singer,40, rocked a black one-piece swimsuit on the deck of the Caravelle while enjoying a passionate kiss with a shirtless Trudeau, who wore only a pair of jeans for the yacht day.

Another snapshot showed the former Canadian Prime Minister, 53, cradling the hitmaker’s rear end as they embraced on the yacht’s upper deck.

In yet another photo, Perry, 40, wrapped her arms around Trudeau’s neck as he seemingly nuzzled her cheek.

The steamy photos were reportedly taken off the coast of Santa Barbara, Calif. in late September by a tourist on a passing boat.

“She pulled up her boat next to a small public whale-watching boat, then they started making out,” a witness to the encounter told the Daily Mail.

“I didn’t realise who she was with until I saw the tattoo on the guy’s arm and I immediately realized it was Justin Trudeau.”

Reps for Trudeau and Perry did not immediately return Page Six’s requests for comment.

The “I Kissed a Girl” songstress and politician first sparked romance rumors in July, when the pair was spotted on an intimate dinner date in Montreal.

They were also seen enjoying a stroll at Mount Royal Park before images of Trudeau emerged at Perry’s sold-out “Lifetimes” tour in Canada.

In August, a source told the Daily Mail that the romance had already encountered a setback, following the frenzied romance speculation and the media attention surrounding their dinner date.

“She’s busy, he’s busy,” an insider told the outlet. “They have a lot going on, and the newness has worn off.” The source also shared that the pair had texted “nonstop” throughout July.

“But there’s nothing negative about it,” they added. “They just aren’t in constant communication anymore. That could change, but for now, it is what it is. It has cooled off.”

Perry split from “Lord of the Rings” star Orlando Bloom in June after nearly a decade together. They share daughter Daisy Dove, 5.

Trudeau, meanwhile, separated from his wife of 18 years, Sophie Grégoire, in 2023. The former couple shares sons Xavier, 17, and Hadrien, 11, and daughter Ella-Grace, 16.
