Katy Perry — who juggles motherhood with a global pop career and a past stint as an American Idol judge — joined former Canadian prime minister Justin Trudeau for a formal luncheon with former Japanese prime minister Fumio Kishida and his wife, Yuko, on Thursday, Dec. 4, 2025.

Kishida shared a photo of the two couples on X, noting that “Former Canadian Prime Minister @JustinTrudeau visited Japan with his partner and joined my wife and me for lunch.” The image shows both pairs smiling in front of an ornate setting and a festive Christmas tree. See the post on X.

In his caption, Kishida reflected on his past meetings with Trudeau during the latter’s tenure as prime minister and said he’s pleased the friendship endures. The comment underscored their continued diplomatic rapport even after Trudeau left office.

Trudeau responded warmly to Kishida’s post, calling it “great to see” and thanking him for his friendship and steadfast commitment to the international rules-based order and a brighter future for all.

The lunch offered another public moment for Trudeau and Perry, who went public with their relationship earlier in 2025. After weeks of speculation — fueled in part by photographs of the couple aboard a yacht — they made a joint appearance in late October in Paris, marking their first confirmed outing together.

Until Kishida’s post and Trudeau’s reply, the pair had largely avoided addressing their romance on social platforms. One fan quipped on Trudeau’s reply that this might be “the craziest hard launch in the history of the free world,” capturing the mix of celebrity and geopolitics in the moment.
