In December 2018, Gyllenhaal was officially linked to French model Jeanne Cadieu, according to Us Weekly. The two traveled together in London and Greece that summer, per Daily Mail but weren't confirmed as a couple until months later.
Cadieu is Gyllenhaal's longest relationship, and the two remain mainly private about their personal and romantic life. The pair have been spotted in public a handful of times since they started dating, most recently at The New York Film Festival's premiere for "The Lost Daughter" in September 2021, which Maggie Gyllenhaal directed.
Gyllenhaal seldom speaks about his relationship with Cadieu, but the actor did briefly touch on his girlfriend in an interview with Esquire in February 2022, saying, "In a lot of ways, we're family . . . I'm in a relationship that is full of love and support. I feel so at ease."
