Katy Perry’s sun-kissed skin was on Justin Trudeau’s mind.

The former Canadian Prime Minister made sure the “California Gurls” singer was protected at all costs while boating in the South of France.

Perry, 41, looked completely at ease as her boyfriend lovingly slathered sunscreen down her dress as the couple embarked on a romantic sunset cruise with friends.

The “Dark Horse” singer rocked a baby blue bodycon dress for the outdoor adventure, and tied her brown hair back into a slick bun with brown shades over her eyes.

Trudeau, 54, sported a pair of khaki slacks, a forest green button down and classic Birkenstock sandals. The couple also enjoyed time at Club 55 during their South of France getaway, where they took a dip in the water and sipped drinks. 

On the heels of their one-year anniversary, the couple only recently made their red carpet debut.

Trudeau proudly walked beside his girlfriend for the premiere of “Katy Perry: The Lifetimes Tour – Live from Paris” at the Tribeca Film Festival in June.

“I am very in love,” she told moderator Tomás Mier before reflecting on the Paris concert.

“Actually, that show was after I met the love of my life, and so I felt very anchored by that because I’m a little bit like a rainbow kite,” she said.

Katy Perry was previously engaged to Orlando Bloom, while Justin Trudeau ended an 18-year marriage in 2023. (Backgrid)

The power couple began dating nearly one year ago after first being spotted dining together at Le Violon in Montréal in July.

At the time, a source told The Sun that the politician “has been single for a while and has enjoyed getting to know her.”

“He is feeling that talking to her and getting to know her is very refreshing, like a breath of fresh air in his life,” the source continued. “He was happy to connect with her so well, and that she appreciates him being a normal, respectful person who was very understanding of her recent separation from Orlando Bloom.”

Perry and Bloom confirmed their breakup last summer after more than a decade together, while Trudeau separated from his wife of 18 years, Sophie Grégoire, in 2023.

“They are interested in each other, but it will take a while to see where this goes,” the source said. “She is traveling around the world, and he is figuring out his life now that he is no longer prime minister of Canada, but there is an attraction. They have a lot in common.”

After Perry officially launched her relationship with Trudeau on social media in December, a source told People that the former prime minister’s persistence paid off.

“The only reason this turned into something real is because Justin has been so persistent,” the source said at the time. “She wasn’t looking to date when they first hung out and she certainly wasn’t looking for a boyfriend.”

Perry and Trudeau went on their first date one year ago in Montreal. (Backgrid)

“He’s shown her over and over again that he genuinely wants to see her,” the source said at the time. “He’s flown all over the world to spend time with her while she toured. She likes spending time with him.”

The source concluded, “She’s flattered that he’s made such a big effort, and she’s excited to be dating him.”
