Gigi and Bella Hadid Introduce Their 23-Year-Old Half-Sister Aydan Nix

Gigi and Bella Hadid are sharing that they have a third sister.

The supermodel sisters announced that they have a 23-year-old half-sister named Aydan Nix, in a statement to the Daily Mail on Thursday, May 29.

Aydan is the daughter of Mohamed Hadid and Terri Hatfield Dull. Gigi, 30, and Bella, 28, revealed that Aydan was born after Mohamed’s “brief romance” with Dull — and after Mohamed, 76, and Yolanda Hadid divorced in 2001.

Their statement explained that Aydan was born and raised in Florida, and grew up with “the man she lovingly knew as her father until his sudden passing when she was 19.” 

But after his death, Aydan took “a genetic test out of curiosity,” and she would soon realize her “biological connection” to the Hadid children. “We first connected in late 2023, and from that moment on, we’ve 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,” the statement 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,” the statement concluded.

The Daily Mail reported that Mohamed and Dull’s relationship ended before she discovered she was pregnant with Aydan. But, he allegedly “always knew” about his youngest daughter. Though he reportedly has “not provided” her with financial support, per the outlet. 

A family source told the outlet that Mohamed is “cordial and pleasant” with his sixth child. “There’s mutual respect,” the source said, per the outlet. “But there’s also discretion.”

The outlet reported that he was expected to attend Aydan’s college graduation from the Parsons School of Design in May, but reportedly canceled around a week before. The Parsons graduate hopes to work in the fashion industry as a designer, stylist and influencer.

Mohamed shares Gigi, Bella and son, Anwar Hadid, 25, with ex-wife, Yolanda. He also shares daughters Marielle, 44, and Alana, 41, with his first wife, Mary Butler.
