See photos of Katy Perry and Justin Trudeau passionately kissing and cuddling on singer’s yacht

‘Cause baby, he’s a firework!

Katy Perry and Justin Trudeau were snapped smooching on the pop star’s yacht, confirming recent rumors about their relationship.

In the photos, which were taken in September, the “Roar” singer, 40, wore a sleek one-piece swimsuit on the deck of the Caravelle while the former Canadian Prime Minister, 53, was just clad in a pair of jeans.

The couple enjoyed a passionate kiss, and at one point, Trudeau cradled Perry’s bottom as they hugged on the upper deck.

The photos were reportedly taken off the coast of Santa Barbara, Calif., by an eagle-eyed tourist.

“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 realize who she was with until I saw the tattoo on the guy’s arm, and I immediately realized it was Justin Trudeau.”

The couple first sparked dating rumors in July, when they were spied enjoying an intimate dinner in Montreal.

Trudeau was also spotted in the crowd at Perry’s sold-out Lifetimes tour in Canada.

However, insiders have noted that it’s not anything serious just yet.

“She’s busy, he’s busy,” an insider shared. “They have a lot going on, and the newness has worn off,” although the two did text “nonstop” throughout the month of July.

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

The “Dark Horse” singer split from Orlando Bloom in June after nearly a decade together. They share daughter Daisy Dove, 5.

Before Bloom, she was briefly married to controversial comedian Russell Brand.

Trudeau, for his part, 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.
