Turner and Jonas began dating after the musician reached out to her on Instagram in 2016. "We had a lot of mutual friends. And they'd been trying to introduce us for a long time," the actor previously told Harper's Bazaar UK. "We were following each other on Instagram and he direct-messaged me one fine day, out of the blue."
In October 2017, the pair announced their engagement on Instagram. Alongside a photo of their hands, which featured a close-up of Turner's ring, Jonas wrote, "She said yes." Turner wrote, "I said yes" in her post.
Turner and Jonas tied the knot twice. First, they wed in an impromptu wedding ceremony in Las Vegas in May 2019, and one month later, they had a more formal ceremony at the Chateau de Tourreau in Sarrians, France. However, four years later, in September 2023, Jonas filed for divorce from Turner. During their time together, they welcomed two children, Willa Jonas (born July 2020) and another daughter (born July 2022) whose name has not been publicly revealed.
The former couple are currently in the midst of a divorce battle. In October 2023, after some back and forth, the pair reached a temporary custody agreement.
