Jack has been very open about his musical chemistry with the artists he works with.
In an in-depth interview with TIME in October 2024, Jack explained how his musical process flows when working with some of the top female artists in the industry.
"It's pretty obvious who's killing right now,” he said. “I feel like we've finally arrived at this place of people just liking what they like and the leading source being authenticity and soul. The people who are really happening are people who've been f—king grinding and developing this amazing sound and perspective. I feel heartened by it.”
“It's been such explosive years for those three, and I think they have something very powerful in common, which is serious f-cking years put into the craft,” Jack said referring to working with Sabrina Carpenter, Charlie xcx and Chappell Roan.
I've been on Sabrina forever,” he shared. “It’s a source of f—king pride, man. But it's also like she's been killing it forever—just now everyone agrees—which may be for some people to exonerate. Someone like Charli, I've known her forever. Bleachers came out around the same time that she did. You put it all together, and it's people having these moments come from just pushing this boulder further up the hill.”
Jack’s wife, actress Margaret Qualley, got candid about the couple’s marriage following their March 2023 marriage.
In an August 2025 cover story for Cosmopolitan, Margaret spoke lovingly about Jack and their two-year marriage. “In every other relationship I’ve ever been in, I still felt really lonely because I wasn’t with my person, and it’s like I was seeking something,” she told the outlet. “I don’t feel like that anymore. Jack makes me feel safe and comfortable.”
“I spent so many years trying to be someone’s perfect girl, and that girl changed over and over again,” Margaret continued. “But I can’t lie to Jack. I can’t be that for him — he’d see through it. So I just have to be myself. He’s been the person I’ve pictured my whole life. And I’m not even saying that metaphorically.”
“Falling in love with Jack was the biggest feeling I’ve ever felt,” Margaret told the outlet. “We met right as COVID was ending, at the first party I’d been to. We saw each other on a roof, and we just started talking and never stopped.”
