Hadid then went on to admit that she "loved" her athletic physique at the time and although walking the show helped to boost her profile, she was only ever given looks that "covered up" her body in fashion gigs that followed.
"I knew how hard I worked to have those muscles, to be curved in those places - I kind of miss it now," she continued. "At the time, people were hard on me and tried to say that I didn't have a runway body."
Back in December 2016, Hadid revealed that her body "changed like crazy" after suffering from a Hashimoto's disease - a debilitating condition which leads to fatigue, increased sensitivity to cold, depression and muscle weakness.
"My metabolism actually changed like crazy this year," she said at the time.
But Hadid doesn't see the runway in her future forever, as the model hopes to settle down and start a family one day.
The A-list couple first called it quits back in March 2018 by posting break-up statements on Twitter.
"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," Malik wrote.
"She has such an incredible soul. I'm grateful to all of our fans for respecting this difficult decision and our privacy at the time, we wish this news could have come from us first. We love you all."
So fans (read: us) were pleased to see the duo reunited once more in January 2020.
Confirming their romance, Hadid shared a photograph of the British singer on Valentine's Day via the model's second Instagram account - a starry page dedicated to her disposable photographs.
