Following Lawrence's split from Aronofsky, the actor began dating the art dealer in June 2018. The two keep their relationship private, but in January 2019, Lawrence's rep confirmed to People that they were engaged. During a June 2023 appearance on "Chicken Shop Date," Lawrence called the proposal "terrifying, but very, very exciting." She recounted, "I didn't say what I wanted to. I, like, imagined it a million times, and then I ended up just going, 'What? What? What?' And then going, 'Thank you, thank you, thank you.' "
Nine months later, the couple tied the knot at the Belcourt mansion in Rhode Island, though in a Nov. 2, 2022, interview with The New York Times, Lawrence revealed that she came close to stopping the wedding before it could happen due to her conflicting feelings about commitment.
"When you don't fully know yourself, you have no idea where to put yourself," she told the publication. "And then I met my husband, and he was like, 'Put yourself here.' I was like, 'That feels right, but what if it's not?'"
She added: "Then I went back, and when I'm home with my husband making this family, I'm so happy I stayed. I'm so happy I didn't freak out and cancel the wedding and run away and go, 'I'll never be taken down!'"
On April 20, 2022, People confirmed that the actor and the art-gallery director had welcomed their first child together, a baby boy named Cy.
