Gigi and Bella Hadid Reveal They Have a 23-Year-Old Half-Sister

The RHOBH daughters said they met their father's sixth child, Aydan Nix, in late 2023

The Hadids have welcomed an “unexpected” family addition.

On Thursday, May 29, supermodel sisters Gigi Hadid and Bella Hadid confirmed they had another half-sibling they were previously unaware of. The Real Housewives of Beverly Hills daughters said their half-sister, 23-year-old Aydan Nix, is the child of their father, Mohamed Hadid, and Terri Hatfield Dull.

“Over 20 years ago, our dad, while single, had a brief relationship that led to a pregnancy,” Gigi and Bella said in a joint statement to the Daily Mail. 

When did Gigi and Bella Hadid learn they had another half-sibling?

Gigi and Bella confirmed that Mohamed and Terri’s relationship began after Mohamed divorced their mom, Yolanda Hadid, in 2001. They said Aydan grew up in Florida and was raised by a “man she lovingly knew as her father until his sudden passing when she was 19.”

After Aydan’s family loss, she reportedly took a genetic test “out of curiosity,” and discovered she was biologically related to the Hadid family. Gigi and Bella said they first connected with their half-sister in late 2023 and have since “embraced Aydan with open arms.” 

“She’s spent time with all of us, including our dad, and we’ve cherished this unexpected and beautiful addition to our family,” they continued. “As siblings, we’ve had many open and loving conversations — with Aydan included — about how to support and protect her. Aydan and her family value their privacy, and we fully respect that. We kindly ask others to do the same and honor her wish and right to her anonymity as she continues her life as a young woman in New York."

Who is Mohamed Hadid's fifth daughter, Aydan Nix?

According to the Daily Mail, Aydan recently graduated from the Parsons School of Design in Manhattan. She is said to be a fashion designer/stylist and an aspiring influencer. 

The outlet reported that Terri learned she was pregnant with Aydan after her relationship with Mohamed had ended.

Who are the Hadid siblings?

 

Yolanda and Mohamed got married in 1994 and went on to welcome three children together: 30-year-old Gigi, 28-year-old Bella, and 25-year-old son Anwar Hadid. Mohamed also has two daughters — Marielle Hadid and Alana Hadid — whom he shares with his first wife, Mary Butler. The Hadid siblings have all worked in the fashion/design business.

“I think my whole family just loves fashion because there is so much to play with in that world,” Marielle told The Daily Dish in 2016. “There are really no boundaries here, and we are drawn to that idea. I think that we are creatives and, all in our own ways, fashion has just allowed us to be ourselves, which is so fulfilling. To do what you love and get paid for it is such a great experience.”
