Gigi and Bella Hadid Reveal Secret Half-Sister Aydan Nix, 23, Discovered Through DNA Test in 2023

May 30, 2025 | New York City — In a heartfelt revelation that has captivated fans worldwide, supermodel sisters Gigi and Bella Hadid have introduced their 23-year-old half-sister, Aydan Nix. The news came as a surprise even to the Hadid family, who only connected with Aydan in 2023 following a DNA test.

Born from a brief relationship between real estate mogul Mohamed Hadid and Terri Hatfield Dull, Aydan grew up in Florida, unaware of her true parentage. Raised by a man she believed to be her father, her world shifted when he suddenly passed away when she was 19. It was only after taking a DNA test that she discovered her biological link to the Hadid family.

“Over 20 years ago, our dad, while single, had a brief relationship that led to a pregnancy,” said Gigi (30) and Bella (28) in a joint statement to the Daily Mail.

Now based in New York, Aydan is a Parsons School of Design graduate and emerging fashion designer. Since discovering her famous half-siblings, she has spent time with Gigi, Bella, and their father, Mohamed Hadid. While Mohamed was aware of Aydan’s existence, sources say he had limited involvement in her life, though their relationship is now described as "cordial" and "pleasant."

“We’ve cherished this unexpected and beautiful addition to our family,” the Hadid sisters said, adding, “As siblings, we’ve had many open and loving conversations—with Aydan included—about how to support and protect her.”

The sisters emphasized Aydan’s wish to lead a private life away from the intense media spotlight. “Aydan and her family value their privacy, and we fully respect that,” they added. “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.”
