Santa Barbara photos showed Katy Perry, 41, and Justin Trudeau, 54, kissing and lounging on a picnic blanket during a weekend park date overlooking the Pacific.
The outing came just before Perry resumes summer festival touring abroad, with the pair also seen driving around town together in an electric vehicle.
Their public romance has accelerated in recent weeks after a red-carpet debut at the Tribeca Festival and another joint appearance in Los Angeles for the FIFA World Cup opening ceremony.
The couple were first linked in Montreal nearly a year ago; Perry split from Orlando Bloom last summer, while Trudeau separated from Sophie Gregoire in 2023.
