The Euphoria and White Lotus star Sydney Sweeney was recently spotted enjoying some summertime fun at her family’s lake house in northern Idaho. But what got fans talking? A mystery man who seemed to be more than just a friend.
Sweeney, 27, looked relaxed and happy as she spent time with a group of close friends and family. Photos captured her laughing, splashing in the water, and riding a jet ski — all while getting pretty close with her unidentified companion. At one point, he was holding her by the waist as they cruised around on the water, and later, the pair disappeared into a quiet cove with a rope swing, where he encouraged her to jump in.
Their chemistry? Not subtle.
Sweeney was rocking a sleek black one-piece swimsuit, while the mystery guy kept it casual with swim trunks, sneakers, and a life vest. They were having a blast, and the internet is now doing its favorite thing: speculating.

This mini-vacation comes right after Sweeney faced some backlash for her recent American Eagle ad campaign. Critics online accused the brand — and by extension, Sweeney — of promoting content with racially insensitive undertones. The controversy stirred up social media, but if Sweeney’s lakeside mood is any indicator, she’s brushing it off and keeping her focus on what’s next.
And a lot is happening on the career front. Her upcoming psychological thriller The Housemaid, directed by Bridesmaids filmmaker Paul Feig, has been building serious buzz. In it, Sweeney plays Millie, a young woman who gets caught up in a twisted web while working for a wealthy family. The project could mark another major turning point in her already red-hot career.
On the personal side, the actress has been making headlines since calling it quits with her longtime fiancé, Jonathan Davino, a producer she’d been dating since 2018. Since then, rumors have linked her to co-stars Brandon Sklenar and Glen Powell — especially after steamy on-screen chemistry and flirty red carpet appearances — but Sweeney has shut those rumors down.
In a recent interview, she made it clear: “I’m learning a lot about myself, spending more time with my friends. And I’m loving it.”
So, who is this new lake house companion? For now, his identity remains under wraps, and Sweeney hasn’t commented. But the photos say a lot — and fans are watching closely to see if this lakeside fling turns into something more.
