The Hadid family are riddled with fame.

Two members have become some of the most famous names in modelling in the past decade with siblings Gigi, Bella and Anwar all landing major runway and campaign jobs – earning them a combined net worth of more than US$58 million.

They’re the children of Dutch model Yolanda Hadid and Jordanian-American real estate developer Mohamed Hadid, who married in 1994, and are both famous in their own rights.

From modelling careers to reality TV shows and advocacy for Lyme disease, the family are very busy, and lead very public lives. But outside of their work, the Hadids keep their private lives as private as possible.

Here is what we know about each of them about what they don't share with the world.

Gigi Hadid.

Gigi, born Jelena Noura Hadid in 1995, began modelling when she was two years old with Baby Guess, before pausing to concentrate on her education. In 2011, Gigi returned to modelling, with her breakthrough coming after her New York Fashion Week debut in 2014.

Since then she’s walked for major designers including Marc Jacobs, Chanel, Versace, Balmain, appeared onVoguecovers around the world and walked in three Victoria’s Secret Fashion Shows.

After moving to New York for her career, Gigi was diagnosed with Hashimoto’s disease, an autoimmune disease that destroys the thyroid.

“Most people get Hashimoto’s when they are middle-aged. I got it very early,” Gigi told Elle in March 2019. “In high school, I had a lot of water retention. Even after extra workouts, I had bloat that wouldn’t go away. And I was always tired. That was tough.”

From 2013 to 2015, Gigi dated Aussie pop star Cody Simpson. They had a pretty amicable breakup, and later that year Gigi moved on to a short-lived relationship with Joe Jonas.

They broke up after about five months together in November and in December she began dating formerOne Directionmember Zayn Malik. Gigi even starred in Zayn's debut music video forPillowtalka month later, and they appeared on the August 2017 cover ofVogueas a couple – only the third ever couple to do so.

They broke up in March 2018, then reconciled three months later. In November that year they split again, but reunited in December 2019, after Gigi briefly datedThe BacheloretteUS' Tyler Cameron.

In 2020, Gigi confirmed onThe Jimmy Fallon Showshe was pregnant with her and Zayn's first child after rumours started circulating about the couple expecting.

"Obviously, you know, we wish we could’ve announced it on our own terms, but we’re very excited and happy and grateful for everyone’s well wishes and support so…" she said at the time.

The pair named their daughter Khai Hadid Malik.

Since her birth, the parents have gone to extreme lengths to maintain their daughter's privacy – which hasn't always been easy.

In 2021, things came to a boiling point between Gigi and Zayn after a feud between the singer and Yolanda escalated into an alleged physical attack.

According to TMZ, the pair had an altercation after Yolanda allegedly barged into the home he and Gigi shared with their daughter, without calling beforehand or knocking on the door.

"Zayn felt Yolanda was acting like the house was hers and ignoring his position as the boyfriend of Gigi and father of their little girl," a TMZ report said.

Court documents filed in Pennsylvania stated that Zayn had filed a "no contest" plea to four counts of harassment, meaning he "agreed not to contest" the charges.

The legal filings alleged that Zayn swore at Yolanda and ordered her to "stay away" from his daughter during an argument at his and Gigi’s home in Pennsylvania. He then allegedly "shoved [Yolanda] into a dresser causing mental anguish and physical pain."

Right before the reports emerged, Zayn released a statement on Twitter, where he explained he'd had an "argument" with a member of Gigi's family.

"As you all know I am a private person and I very much want to create a safe and private place for my daughter to grow up in. A place where private family matters aren't thrown on the world stage for all to poke and pick apart," Zayn’s statement began.

"In an effort to protect that space for her, I agreed to not contest claims arising from an argument I had with a family member of my partner's who entered our home while my partner was away several weeks ago," he wrote.

He continued, "This was and still should be a private matter but it seems for now there is divisiveness and despite my efforts to restore us to a peaceful family environment that will allow for me to co-parent my daughter in a manner in which she deserves, this has been 'leaked' to the press."

While neither Zayn nor Gigi have said anything since the events that unfolded in 2021, the pair have maintained a strong co-parenting dynamic.

In an interview with NBC News'Sunday Today With Willie Geist,Gigi labelled her daughter a "genius" who entered the "terrible twos" stage with a fierceness.

"Oh, [she's so] so mobile, from so early in the morning," she said. "So mobile. Jumping off things. Very brave, which is great but, you know. We're practising doing dangerous things carefully. That's what I'm gonna go for."

She continued, "I think she's a genius. But I think that's what everyone says about their kid. It's so much fun. The more that she talks and understands and remembers, it just gets more and more fun. And she's a blessing."

As well as being a full-time mum of one, Gigi launched her own clothing brand, Guest In Residence in 2022.

The label sells a range of loungewear, everyday staples and luxury knitwear.

Bella Hadid.

Gigi's younger sister Bella was born in 1996. As a teenager, Bella competed in equestrian sports and dreamed of competing at the 2016 Rio Olympics, before moving to New York for modelling and to study photography at Parsons School of Design.

She dropped out as her modelling career took off, but has said she'd be interested in completing her studies to take on fashion photography after she is done in front of the camera.

Like her sister, she made her debut at New York Fashion Week in 2014, which led to a successful career in fashion weeks and on magazine covers around the world. In 2016, Bella was voted Model of the Year atmodel.com'sannual awards.

In 2012, Bella was diagnosed with Lyme disease, along with her mother and brother – an infectious disease transmitted through a tick bite. In 2016, Bella accepted an award at the Global Lyme Alliance Gala in New York and spoke of her struggles with the disease.

According to People she dedicated her award to "all the teenagers out t

She explained that horseback riding "was my dream of my life and what I did every single day until I just stopped and realised I didn’t have the brain power to ride horses anymore, so that was the end of that".

At the beginning of 2015, Bella began dating Canadian singer The Weeknd (real name Abel Tesfaye). They made their red carpet debut at the 2016 Grammys, but broke up in November of that year because of conflicting schedules.

After his 10-month relationship with Selena Gomez, Bella and The Weeknd got back together by May 2018, but broke up again in 2019.

In 2021, Bella publicly revealed she was in a relationship with Marc Kalman who is an art director. He has famously worked with Travis Scott for years.

Anwar Hadid.

The youngest Hadid was born in 1999 and began modelling in 2015, aged 15. At 16, he signed to IMG Models and has appeared on the cover ofTeen Vogueand walked in New York Fashion Week.

He was diagnosed with Lyme disease in 2012 – the same year as his mother and sister Bella.

Anwar datedTransformers: Age of Extinctionstar Nicola Peltz from December 2016 to May 2018.

After they broke up, he was spotted kissing his sister's best friend Kendall Jenner.

In 2019, Anwar and Yoni Laham launched a jewellery label called Martyre. The pair design and create unisex pieces that should be "worn by everyone."

Anwar dabbles in music too, releasing his debut albumBLEACHin April 2019, which is reportedly what he bonded over with his girlfriend Dua Lipa, who he began dating in June 2019 before their amicable split in December 2021.

Alana and Marielle Hadid.

Yep, there are other Hadid sisters: Alana and Marielle Hadid are Gigi, Bella and Anwar's half-sisters from their father Mohamed's first marriage to Mary Butler, which ended in 1992.

The eldest, Marielle, was born in 1980. She is a designer and owns a sunglasses brand called Hadid Eyewear with her younger sister Alana.

She has two children, daughter Colette and son Colton, with partner Sammy Aflalo.

Alana, born in 1985, works as a fashion designer in New York.

The sisters are very close with their famous siblings, regularly posting photos and messages of support to each other on Instagram.
