Bella and Gigi Hadid reveal half-sister after their father had secret romance

Two of the worlds most recognisable models have announced a shocking family secret that spans all the way back to 2001.

Gigi and Bella Hadid have been keeping a secret.

The supermodels have a half-sister named Aydan Nix that they just confirmed to the world.

Gigi, 30, and Bella, 28, released a statement about their 23-year-old half-sibling on Thursday, revealing that Nix is the result of their father, Mohamed Hadid’s “brief romance” with a woman named Terri Hatfield Dull.

They also shared that the real estate developer’s relationship with Dull happened after his 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 and Bella told the Daily Mail in a statement.

The sisters also revealed that Nix did not know Mohamed was her dad until recently.

“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,” Gigi and Bella’s statement continued.

The Hadid sisters explained that Nix “decided to take a genetic test out of curiosity,” which led to the shocking discovery that she had “a biological connection” to them.

Gigi and Bella said they have known about their half-sister for over a year, sharing that they “first connected in late 2023,” with Daily Mail claiming it happened while Nix was studying abroad in Paris last year.

Since then, the sisters said Nix has “spent time” with the entire family, including Mohamed, 76, adding they have “embraced” her “with open arms”.

“We’ve cherished this unexpected and beautiful addition to our family,” Gigi and Bella continued before pleading for Nix’s privacy.

“As siblings, we’ve had many open and loving conversations— with Aydan included — about how to support and protect her,” the sisters said. “Aydan and her family value their privacy, and we fully respect that. We kindly ask others to do the same and honour her wish and right to her anonymity as she continues her life as a young woman in New York.”

Nix is a recent graduate from the Parsons School of Design in Manhattan and living in the city, with dreams of reportedly becoming a designer, stylist and aspiring influencer, according to Daily Mail.

The outlet, which posted the shocking family secret on Thursday, claimed that Mohamed’s relationship with Dull ended before she discovered she was pregnant. However, he allegedly “always knew” about Nix but reportedly has “not provided” her with financial support.

A family source told the outlet that Mohamed is “cordial and pleasant” with Nix.

“There’s mutual respect,” they added, “but there’s also discretion.”

The family insider also claimed that Mohamed was expected to attend Nix’s graduation in May but allegedly cancelled the appearance “about a week beforehand.”

Gigi and Bella — who have a brother, Anwar Hadid, 25, from Mohamed and Yolanda’s marriage — have been photographed with Nix on various occasions, but no one except those close to the family was aware of the connection until now.

Besides the kids he shares with Yolanda, Mohamed is also dad to daughters Marielle, 44, and Alana, 39, whom he welcomed with his first wife, Mary Butler.
