According to Turner’s March 2019 interview with Harper’s Bazaar UK, it all started in 2016 with a DM. When asked how the two met, Turner explained that friends intended to set them up, but Jonas was the one who made the first move. “We had a lot of mutual friends,” she explained, “and they’d been trying to introduce us for a long time. We were following each other on Instagram and he direct-messaged me one fine day, out of the blue.”

The first time Jonas and Turner were photographed together was in a group photo from Halloween 2016, which was posted by a friend on Instagram. Less than a week later, the two were spotted in Rotterdam, Netherlands, at a pre-MTV EMAs Kings of Leon concert, where onlookers caught them looking cozy. “They were really close together,” a source told People. “I didn’t look very often... [but] the two or three times I was watching they were kissing. She was all smiley and he looked really sweet.”

Later on in the month, Jonas and Turner attended a wedding in Malibu, where they snapped some goofy photo booth pics with friends, including Jonas’ brother Nick.

In early December, the Daily Mail published pics of Turner and Jonas going for a stroll with Turner’s parents and brother in London. Two days later, People reported that the two were officially a couple. “They’re dating exclusively,” a source told the mag. “He was playing the field, but he really likes her and is willing to settle down for her.”

On New Year’s Day 2017, Turner shared her first photo of Jonas on her Instagram, which was a solo shot of the JoBro posing on a boat in Miami. “Miami Daze,” she captioned the pic.

Less than a week later, Turner and Jonas attended the CAA’s pre-Golden Globes party as a couple, but they decided not to walk the red carpet together at the awards show two days later. When asked about her maybe-relationship by Extra TV host Mario Lopez, Turner played it coy. “I’m not saying anything,” she said. “I’m very happy.”

Turner and Jonas walked the red carpet together for the first time at the 2017 Met Gala, though they didn’t pose for any couple pics. They also attended Katy Perry’s after-party at the Boom Boom Room, where Nick Jonas snapped a cute pic of the couple and captioned it, “These two ❤️.”

When asked about her relationship a few months later by The Sunday Times, Turner simply replied, “I’m in a relationship, but it’s a very private relationship.”

Jonas and Turner took their relationship to the next level in September 2017 when they adopted a husky puppy together, whom they named Porky Basquiat. Turner shared a cute pic of the new pup on Insta, which she captioned, “Meet the newest addition to the krew @porkybasquiat 🐶.”

On Oct. 15, the couple announced their engagement on Instagram with matching pictures, which showed only their hands and Turner’s sparkly new pear-cut diamond. “She said yes,” Jonas captioned his picture, while Turner’s caption read, “I said yes.”

The engagement, according to Us Weekly, was a total surprise. “They are madly in love,” a source told the magazine. “She’s young but mature and comes from a small English town, so it’s not that out of the ordinary and age doesn’t create an issue. They are really good together and his friends and family love her and vice versa, but they aren’t rushing to get married.”

Nearly six months after announcing their engagement, an interview with Turner was published in Marie Claire, where she explained that getting engaged didn’t feel like an achievement, but rather a “lovely” new part of her life. “There’s this weird misconception that being married is the greatest thing that’ll ever happen to you,” she said. “But I’ve always found that my career is something I work for, and when I achieve something, there’s a sense that this is the greatest thing I’ll do in my life. It’s lovely to be engaged. Not like I achieved anything, but I found my person, like I’d find a house that I love and want to stay in forever.”

A few days after the Marie Claire interview was published, Jonas and Turner added a new member to their family: another Alaskan Klee Kai pup named Waldo. “Welcome to the family @waldopicassojonas 🐶 ♥️ 💫,” Turner captioned a picture on Instagram, showing Waldo and Porky Basquiat together. Unfortunately, Waldo was tragically killed in July 2019 when he escaped from his dog walker and was struck by a car in New York City. Jonas and Turner commemorated their late doggo with matching tattoos of Waldo, which they both got inked on their right forearm.

Almost a year after getting engaged, the couple got their first set of matching tattoos, which were inspired by Toy Story. Jonas got one on his wrist that reads, “To infinity,” while Turner’s matching tattoo, which is also on her wrist, reads, “& beyond.”

After the 2019 Billboard Music Awards on May 1, Turner and Jonas shocked fans by taking off for Las Vegas and tying the knot at A Little White Wedding Chapel. An Elvis impersonator officiated, and Diplo took to Instagram Live to share the super-secret ceremony with his followers. They exchanged Ring Pop wedding bands, and though everyone thought Turner and Jonas were pulling a fast one, People later confirmed the wedding was totally legit.

In an interview with Porter, Turner clarified that the Vegas wedding had been planned ahead of time, but they had intended to keep it secret. (Way to go, Diplo.) “Marriage is a private thing between two people,” she added, “and I think that’s how it should always be. It’s not about the dress, it’s not about the food. It’s about being husband and wife, and being dedicated to each other forever.”

Two months after their Vegas ceremony, Jonas and Turner had a second, more formal celebration on June 29 at the Château de Tourreau in Sarrians, France. Just like with their Vegas nuptials, the couple hoped to keep things under wraps, but this time, Dr. Phil accidentally spilled the beans. After Turner posted an Instagram of her and her hubby in Paris on June 22, Dr. Phil commented, “Easy now! 1 week to go! Ha! See you at the wedding!” (*Face palm*)

Afterward, the two jetted off to the Maldives for their honeymoon.

Turner kept her first pregnancy under wraps, only posted pics of herself a few months after she gave birth to her and Jonas’ daughter Willa in July 2020.
