Just a few months later they were spotted snuggling on a sofa, hanging out together and generally resuming couple-based-activities, sparking rumours that their relationship is back on.
Now the pair appear to be more loved up than EVER before as Gigi Hadid posted an Instagram snap with the following caption, "flyin home to my happy place." The accompanying snap shows Gigi snuggling up to a topless Zayn sitting behind her. In less than 9 hours, the post has garnered a casual 4.7 million likes, naturally.[ id="BpNual8HTSA"]
Earlier this year, ZiGi fans were treated to a cute AF snaps from Gigi's mum and Real Housewife of Beverly Hills star, Yolanda Hadid, just posted a snap of the couple celebrating Eid Mubarak on her Instagram story.
Although they've remained coy about what they've been up to since they rekindled their romance, they recently gave us the Instagram official confirmation we've been waiting for - and everyone knows that's how couples do things in this day and age.
Gigi took to her Instagram Stories to confirm that they'd been on holiday together, and they look very loved up indeed.
It's not clear where they've been vacay-ing, but it looks LUSH. Aw, we're glad they could work things out.
Back in July, Gigi stood up against people who labelled their relationship as 'fake'.
The 23-year old model made an appearance in the comments of an Instagram account that goes by the handle '@exposingfakeasszigii'. After the ordeal, naturally, the account went private, but unfortunately for the owner of the account - the internet already had their screenshots.
The account is supposedly dedicated to posting substantiated 'confessions' about the couple, and recently uploaded a photo of Gigi and Zayn claiming that everything they do is for 'promo', adding: "Fact is that Zayn is not going to follow Gigi or ever going to post her picture on his Instagram again." (FYI, he unfollowed her during their break earlier this year.)
The post caught Gigi's eye as she left a comment asking them to stop tagging her in photos every day.[ id="1014186853694689281"]
"It's just negative," she wrote. "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."
One particular part of the essay-length clapback that made us chuckle was that she didn't need Zayn to follow her because he "has her eyes on his chest" (not an exaggeration, this is an actual tattoo he has).
"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" she then went on to add.
Later on, Gigi then responded to another comment which suggested she should have DM'd the account, rather than blast them in the comments. Ok hold on a second - someone just called her out for standing up for herself against a troll that targeted her relationship? We seriously feel for Gigi right now.
"I'm sorry if it came off immature, I'm just trying to open a dialogue so people understand that their words are hurtful and not just an 'anonymous confession,'" the model explained.
While Gigi's being pretty open about her thoughts, you aren't going to get that kind of clarification from Zayn. In June 2018, he insisted on 'not labelling' their relationship as they're both 'adults'. Fair.
In an interview with GQ, he explained:
"We're adults. We don't need to put a label on it, make it something for people's expectations."
He also divulged how Gigi helped him get past his teenage angst, saying, "I had a very negative outlook on things. That might have been adolescence or testosterone or whatever the f*ck was running through my body at the time. She's helped me to look at things from a positive angle."
During the interview, Zayn further revealed that he's bought a farm in Pennsylvania, not far from where Yolanda Hadid lives. He and Gigi have also purchased a horse together, named Cool, and he now spends his time growing cucumbers, cherries and tomatoes. Casual.
Whatever is going on between them, they seem happy, and that's totally cool by us.
Taking to Twitter at the time of their breakup, the former One Direction star confirmed that he and his supermodel girlfriend had broken up after two years together.
Rumours started to swirl that the 25-year-old singer and 22-year-old model had gone their separate ways and, just hours later, Zayn posted this on his Twitter account.
His post read: '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'
A source told The Sun: 'They are no longer a couple but they do remain close and are supportive of each other. The reality is that they’ve grown apart, having been together for a long time. They have crazy work schedules that would put pressure on any relationship.'
Zayn and Gigi became official back in January 2016, six months after he and Little Mix star, Perrie Edwards, broke up.
We can't wait to see where their relationship goes from here.
