Zayn Malik and Gigi Hadid are reportedly expecting their 1st child together. Here's everything you need to know about their relationship.

The former supermodel confirmed that her daughter was pregnant to Dutch media outlet RTL Boulevard. People translated the interview.

"Of course we are so excited," she said, adding, "I'm excited to become an Oma in September especially after I lost my mom so recently. But this is the beauty of life: One soul leaves us and a new one comes in. We feel very blessed."

News broke that the 25-year-old model and the 27-year-old singer were expecting their first child together. Sources close to the family confirmed the news to TMZ, Entertainment Tonight and Us Weekly.

Hadid was reportedly 20 weeks pregnant when the source revealed the pregnancy news.

"Gigi has kept the secret close to her family and friends for a while as she's only a few months along. Once Gigi and Zayn got back together at the end of last year it was like they never skipped a beat and knew what they had was special. The couple and their families are overjoyed," sources told ET.

The next day, TMZ reported that the couple is expecting a baby girl.

"Had the sweetest day celebrating my 25th birthday with my quarantine family, who made it so special for me, along with all the love I felt from all over the world!" she wrote on Instagram along with a picture of her and Malik.

The supermodel also shared photos with her sister Bella and her mother Yolanda.

Paul took to Twitter to insult the musician and said he almost got into a fight with Malik.

"Almost had to clap up zane from 1 direction because he is a little guy and has an attitude and basically told me to f--- off for no reason when I was being nice to him," he tweeted, adding, "Zane ik you're reading this... stop being angry cause u came home alone to ur big a-- hotel room hahaha."

He has since deleted the tweet, however Hadid replied to Paul's message to defend Malik.

"Lol cause he doesn't care to hang w you and your embarrassing crew of YouTube groupies ..?" she tweeted, continuing, "Home alone with his best friends like a respectful king cause he has me, sweetie. Unbothered by your irrelevant ugly a--. Go to bed ..."

They stepped out with the model's sister Bella Hadid and pop star Dua Lipa, who's dating Hadid's brother Anwar Hadid.

"Sunday in the kitchen about to marinate one of my favorites!!! @mammamalik's Chicken Curry Pasta Salad," she wrote on her Instagram story, adding, "Hopefully she'll share the recipe with the world one day."

A source told E! News that Hadid "has always had a soft spot for Zayn and they have a lot of history together."

"They went through a phase where they took time apart and weren't communicating at all, but they have been in touch recently. She is supportive of him. They chat here and there but it's been casual," the source said.

Hadid was first seen spending time with Cameron at DUMBO House in New York City. They were seen on multiple dates around New York City, and Cameron even accompanied Hadid to her grandmother's funeral in the Netherlands.

By September, the couple had reportedly called it quits, and Hadid was single once again.

A source told Us Weekly that the couple broke up once again and said, "They could get back together, but it's over for now."

Another source told the outlet that Hadid "tried hard to make it work," but said that Malik has "a lot of his own issues that she couldn't help him get through."

The source continued, "She cut herself off from all her friends every time they were together. She focused all her time and energy on him, but it just got to be too much."

Entertainment Tonight also spoke to a source about the on-again, off-again couple's breakup.

"Gigi and Zayn have broken up, but not because they don't love one another. After trying for a long time, the couple just couldn't make it work. Zayn has been dealing with personal things for a while and Gigi has become a comfort blanket for him," the source told Entertainment Tonight.

She captioned the since-deleted Instagram photo, "flyin home to my happy place."

After an Instagram user called out Malik for not following Hadid, the model stepped up to defend their relationship, according to E! News.

"Whatever zigi does for promo. Fact is that, Zayn is not going to follow gigi or ever going [to] post her picture on his Instagram again," the account reportedly wrote.

"Seems like u guys tag me in a new post every day … pls stop.. it's just negative, I really have no hard feelings towards you I just know what a beautiful world there is to go out and live in instead of trying to dissect a relationship between two people that you don't even know and that you do not see 99% of," Hadid wrote.

She added, "For someone who is virtually inactive on the app, I don't need his follow- my eyes are tattooed to his chest. The energy you put into this does not serve you our your life in any way kids…. truly 'beating a dead horse.' You guys can call it promo but I just post about my boyfriend like anyone else, whether I support z or he supports me is out of love and excitement for one another. There's nothing to figure out all the time… give it a break."

"We're adults. We don't need to put a label on it, make it something for people's expectations," he said during an interview with GQ.

Malik continued, "I had a very negative outlook on things. That might have been adolescence or testosterone or whatever the fuck was running through my body at the time. She's helped me to look at things from a positive angle."

"Zayn really wants to be with Gigi and has made it clear. He misses her and can't stand being apart," the source told E! News, adding, "Gigi's a little bit more hesitant."

The source explained that the couple broke up because "it wasn't working and nothing has really changed" but said that Hadid "does love him, but she isn't completely sure this is where she wants to be right now."

The report came a month after the couple announced their split.

On March 13, 2018, The Sun reported that the pair had split because of work conflicts. The same day, the pair confirmed the news shortly after on their separate social media accounts.

"Breakup statements often seem impersonal because there is really no way to put into words what two people experience together over a few years .. not only in the relationship, but in life in general. I'm forever grateful for the love, time, and life lessons that Z and I shared. I want nothing but the best for him and will continue to support him as a friend that I have immense respect and love for. As for the future, whatever's meant to be will always be. xG," she tweeted.

Malik also released a statement about the breakup.

"Gigi and I had an incredibly meaningful, loving and fun relationship and I have a huge amount of respect and adoration for Gigi as a woman and a friend. She has such an incredible soul. I'm grateful to all of our fans for respecting this difficult decision and our privacy at this time, we wish this news could have come from us first. We love you all. xZ," he wrote.

The musician wore a head-to-toe Spider-Man outfit, while Hadid dressed up as Black Cat.

"Spidey's girl," she captioned the Instagram photo, adding, "HAPPY HALLOWEEN from #FeliciaHardy, The Black Cat xx."

Yolanda Hadid, a former supermodel, gushed over the sweet couple in an Instagram post, calling them her "family."

"Summer Loving ... #Family," she captioned the black-and-white photo.

Malik also joined the Hadid's family for Eid Mubarak.

Hadid and Malik appeared in Vogue, and this time they graced the cover. Although the magazine gained a lot of attention, people were not happy that the magazine referred to the couple as being "part of a new generation embracing gender fluidity."

Neither Malik nor Hadid has identified as gender fluid, so people thought it was inappropriate that they claimed that title. The magazine eventually apologized for misusing the term.

Malik drew attention to his girlfriend on her 22nd birthday in a since-deleted Instagram post.

"Happy birthday to my everything," he wrote.

During an interview with British Vogue, Hadid spoke about what she and Malik prefer to do when they're not working.

"When I'm in L.A. I mostly stay in because it's my time off and I like being with my boyfriend and doing art and cooking," she said, adding, "We like late night movies, and we order from this amazing place that does lattes and gingerbread cookies. I need coffee to stay up."

Hadid also admitted that she has a habit of falling asleep during their movie nights.

"I'm always like, 'Babe, let's go to a movie.' Then I fall asleep halfway through and he's like, 'You've seen the first half of every movie out there and you have no idea how any of them end,'" she said.

When fans spotted Hadid wearing a gold band on her ring finger, they wondered if Malik had proposed to her. However, they weren't engaged.

People also noticed Malik's new hand tattoo, which said "Love" across his knuckles, and wondered if the ink was a tribute to Hadid.

During an interview on Sirius XM's "Morning Mash Up," Malik was asked about how he landed Hadid as a girlfriend.

"I just asked her. It was pretty straight up," he said, adding, "I just asked her if she wanted to go on a date. I was in New York."

Hadid and Malik were spotted getting dinner with Swift in Paris. Soon after, Malik and Swift announced their new song "I Don't Wanna Live Forever" for the movie "50 Shades Darker."

They were photographed together at the Givenchy runway show.

Hadid posted a Snapchat of her kitchen, which featured matching Nutella jars with her and Malik's names on them.

People reported that Malik and Hadid broke up. However, a source told the outlet that "it seems like it's not totally over."

Weeks later, the duo appeared to be back together as they showed PDA while out in New York City. A source told People that the couple rekindled after Malik "kept incessantly apologizing and wanted another chance."

According to the source, Hadid and Malik had "been working on their communication and being honest with each other."

The source also explained that the breakup came after "they were fighting all the time and Gigi caught Zayn in a handful of lies and couldn't take the mystery anymore, so she dumped him."

The theme of the 2016 Met Gala was "Manus x Machina: Fashion in An Age of Technology." Hadid wore Tommy Hilfiger, and Malik wore Versace.

Malik and Hadid traveled to Naples, Italy to shoot photos for Vogue. In the photos, which were taken by Mario Testino, the couple kisses on a balcony, rides a scooter, and embraces in bed.

Hadid showed Malik's face in the black-and-white photo and added a pink heart.

He also seemingly confirmed the relationship during an interview on the "Zach Sang Show," saying that it was "cool" to have his girlfriend in the "Pillowtalk" music video.

Malik and Hadid surprised everyone when they appeared together in a steamy music video for his debut solo single "Pillowtalk." The couple also flirted on Twitter after the video's release.

The day after the video dropped, Malik wrote, "you seen the video babe ?" adding that she looked fantastic.

"nah musta missed it," she responded, adding, "Jokes.. I wasn't looking at myself, trust me."

Hadid shared a filtered Instagram photo of herself wearing "Z" necklace on Malik's birthday.

She captioned the photo, "ZDAY."

The supermodel posted a black-and-white Instagram photo of Malik holding her kitten. Although she didn't show the musician's face, his tattoos made it easy to determine that it was him in the photo.

The couple confirmed their romance with a black-and-white Instagram photo, which Malik posted on Instagram. The photo has since been deleted.

The duo was spotted holding hands while leaving a late-night spot in Los Angeles weeks after Hadid's reported breakup with Jonas.

After the photos came out, Jonas made a comment about his ex's budding relationship with Malik.

"I think it's interesting that she moved on so quickly, I mean it was definitely very quick," he told Mirror.

Jonas unfollowed both Hadid and Malik on social media, and deleted a photo of him and Malik on Twitter and Instagram.

Hadid and Malik were photographed leaving Justin Bieber's American Music Awards after-party together, leading to speculation that the model and musician were dating.

"It's a very new thing. They're just seeing where it goes," a source told Us Weekly.

Another source told the outlet, "I wouldn't call them boyfriend and girlfriend. But seeing each other? Definitely. He's chuffed."

The couple ended their relationship in November 2015. At the time, they cited scheduling conflicts for their troubles.

"Nothing serious happened...it wasn't a dramatic breakup. It was just hard to make it work with their schedules. They will definitely remain friends," a source told People.

A few months after he split from One Direction, the singer ended his four-year-long relationship with his fiancée Perrie Edwards, a member of the group Little Mix. She claimed that he ended things over text, but Malik later refuted that he did so.

Their breakup led to Little Mix's revenge anthem "Shout Out to My Ex," which includes some digs at Malik.
