Gigi and Bella Hadid Discover They Have a Half-Sister: 5 Things to Know About Aydan Nix

Supermodels Gigi and Bella Hadid are opening up about discovering that they have a half-sister.

The models said that their sibling, Aydan Nix, 23, was born of a brief relationship between their father, Mohamed Hadid, and a woman named Terri Hatfield Dull following Mohamed’s divorce from their mother, Yolanda Hadid, in 2001.

“Over 20 years ago, our dad, while single, had a brief relationship that led to a pregnancy,” Gigi, 30, and Bella, 28, told the Daily Mail in a statement on Thursday, May 29.

According to the sisters, Aydan was “born and raised in Florida, growing up with the man she lovingly knew as her father until his sudden passing when she was 19.” Following her father’s death, Aydan “decided to take a genetic test out of curiosity” and discovered her “biological connection” to Gigi and Bella.

The half-siblings “first connected in late 2023” and the Hadids have since “embraced Aydan with open arms,” the statement said. (Us Weekly has reached out to Gigi and Bella’s representatives for further comment.)

In addition to Gigi and Bella, Mohamed, 76, shares a son, Anwar, 25, with Real Housewives of Beverly Hills alum Yolanda. He also shares two daughters, Marielle, 44, and Alana, 39, with his first wife, Mary Butler.

She has a close relationship with her mom

To mark her mom Terri’s 50th birthday in February 2023, Aydan shared a touching tribute to her mother via Instagram, writing, “She’s the most beautiful person I’ve ever known and ever will know.”

“Sometimes I call her 4 times a day. She always answers the phone,” Aydan wrote, noting that her mom is her “role model and my best friend.”
