Joe Jonas and Sophie Turner just had their first child. See how their relationship has evolved over the last 4 years.

"We had a lot of mutual friends and they'd been trying to introduce us for a long time," Turner told Harper's Bazaar UK during a March 2019 interview. "We were following each other on Instagram and he direct messaged me one fine day, out of the blue."

After talking for a few weeks, they met up in real life in London.

"[We] were all in," Jonas told Dr. Phil in 2019. "We knew it was something unique."

"I expected him to show up with security and everything. I thought, 'He's gonna be such a d---,'" Turner told Elle magazine in a cover story released in March 2020.

The actress said that she was skeptical that it was actually Jonas who messaged her in the first place. As a safety measure, she invited her friends to accompany her.

"I brought all my guy friends to come with me to meet him, because in the back of my mind I still worried that he could be a catfish — or I don't know what," she said. "I just wanted my guy friends with me. I had my rugby boys. I was safe."

Turner went on to say that she met up with Jonas at a "local s---ty bar, dirty, with great music and people throwing up everywhere" and they chatted "for hours."

She added: "It wasn't small talk — it was just so easy. And soon we were, like, inseparable. I went on tour with him."

Turner and Jonas were dressed as a Dalmatian and a rabbit. There was nothing to indicate a romance was burgeoning other than the fact that they were standing near each other.

A fellow concert goer told Us Weekly Turner and Jonas were cuddled up and kissing throughout the show.

From dining in romantic New York City restaurants to going out in LA clubs, Turner and Jonas were frequently popping up around the US.

The photo was captioned simply: "Miami Daze."

This was far from a confirmation of their relationship, but it was clear the couple was spending more and more time together.

"I can't believe you're going out with Joe," Mario Lopez of Extra said.

Turner laughed and seemed taken aback by the direct question.

"I'm not saying anything," she replied. "I'm very happy."

Even though no photos were snapped of them on the red carpet, afterward they were spotted heading to Katy Perry's after party and holding hands.

"These two ❤️ ," Nick Jonas wrote.

This was the closest fans got to a confirmation, because neither Jonas or Turner had shared more photos of themselves since Turner's January post from Miami.

From more outdoor restaurant sightings to New York City walks, Turner and Jonas continued holding hands and kissing in public.

"You do feel like you're living in a fishbowl," Turner said when asked about dating Jonas. "It's frustrating [that] it's the most mundane things that make the news – how boring! There are really no other headlines?"

She also told Marie Claire that she and Jonas had met each other's parents.

"They met through mutual friends and have already done the 'meet the parents' – him joining the Turners in a north London pub; her on a Jonas' family skiing trip," Marie Claire reported.

"I'm in a relationship, but it's a very private relationship," she told the Times of London on July 1.

She also spoke generally about how her life had changed recently, likely in conjunction with her relationship to Jonas.

"I'm happier than I've been in a very long time," she told the publication. "I very much isolated myself for a while and forgot what was fun. Going out with friends, going out to eat, not really having a care. And people I've met recently in my life have drawn me out of that. It really helps you own those insecurities. The things I tortured myself about before, I can forget about."

INSIDER was on hand for the red carpet premiere and after party, and spotted Turner and Jonas holding hands and catching up with fellow "Game of Thrones" couple Kit Harington and Rose Leslie.

Jonas posted a photo from the after party of himself and brother Nick chatting with Harington.

The pup's name is Porky Basquiat, and Jonas got him for Sophie as a gift. They also have another Alaskan Klee Kai named Waldo Picasso, who's the biological brother of Porky.

"Porky is a maniac, a wild man, and Waldo is shy," Jonas told the Today show in 2018.

"I said yes," Turner wrote.

Jonas captioned his photo saying: "She said yes."

Friends and family congratulated the happy couple and the "Game of Thrones" fandom went nuts over the news.

The couple later had a star-studded engagement party with a guest list that included model Ashley Graham, Ansel Elgort, and Tom Holland.

"There's this weird misconception that being married is the greatest thing that'll ever happen to you," the actress told Marie Claire for the 2018 Fresh Faces issue. "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."

She elaborated, saying: "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. There's a sense of peace that comes with finding your person. But there's a drive that comes with your career."

Jonas' wrist reads "To infinity," while Turner has "& beyond," a nod to the famous line spoken by Buzz Lightyear.

In an image shared on Instagram, Turner was seated at a large table with fiancé Joe Jonas, her parents and brother, newlyweds Nick Jonas and Priyanka Chopra, the Jonas parents, and Chopra's mother.

Turner and Jonas also went on a ski trip to Verbier, Switzerland with Nick and Chopra.

The lavish video was filmed at Hatfield House, just outside of central London. The "Sucker" music video also featured $200 million worth of artwork inside.

"I think for the longest time I didn't have a real sense of myself," Turner, who was 13 when she auditioned for the role of Sansa on "GoT," said in a cover story for Glamour UK's spring/summer 2019 issue. "I had a bit of an identity crisis where I was playing all these people and I'd grown up faster than I probably should have done."

The actress went on to say that she credits "a lot" of her happiness to her relationship with Jonas, "who loves me more than he loves himself, and who wants to see me find my own happiness."

Turner added: "That was probably the biggest thing that pushed me to find who I am — and find my happiness in things other than acting."

"I don't think I love myself at all, but I'm now with someone that makes me realize that I do have some redeeming qualities, I suppose," she said during an interview with Dr. Phil for his podcast called "Phil in the Blanks." "And when someone tells you they love you every day, it makes you really think about why that is and I think it makes you love yourself a bit more. So yeah, I love myself."

She added: "I feel safe around him. I won't be judged by him. He's seen the worst."

It took place at A Little White Wedding Chapel, following the Billboard Music Awards, which the Jonas Brothers performed at.

The wedding was officiated by an Elvis Presley impersonator and the guests included celebrities who were present at the BBMAs, like Khalid, country duo Dan + Shay, and the other members of the Jonas family. DJ Diplo was also present and livestreamed the event on Instagram. He later got flack for doing so without asking the bride and groom for permission.

"It was the worst day of our lives," Turner said during an interview with the Times UK in May 2019. "For a second we both had cold feet, then 24 hours later we were both, like, 'Never mind.'"

"In finding myself, I was also able to find a partner," he said. "The impact of falling in love has made me want to be a better man, a better person, and ultimately made me a better brother."

Jonas explained that they chose that destination because it's "mutual ground" for the pair.

"We both have spent a lot of time in France together," he told Dr. Phil in an interview. "It also happens to be one of the most romantic places in the world."

They were joined at the wedding by family members, including Nick Jonas, his wife Priyanka Chopra, model Ashley Graham, as well as Turner's "Game of Thrones" costar Maisie Williams, who served as the maid of honor.

The couple hasn't revealed any details about the event, but Us Weekly reported that Turner wore Louis Vuitton for the ceremony. According to E!, white flowers and glass candles lined the aisles of the venue.

Just Jared, "E! News," and Us Weekly reported that the couple has a baby on the way. "E! News" reported that Turner has been pregnant for approximately four months and according to Us Weekly, her baby is due in the summer.

The stars haven't publicly addressed the reports, but they were photographed shopping for baby clothing in California.

On Monday, TMZ first reported that the two stars became parents to a baby girl named Willa, born in Los Angeles.

"Sophie Turner and Joe Jonas are delighted to announce the birth of their baby," a representative for Turner said in a statement shared with Insider.
