On May 29, 2025, supermodels Gigi and Bella Hadid shared a heartwarming announcement through a family introducing their 23-year-old half-sister, Aydan Nix. This revelation has captivated fans and media, shedding light on a previously unknown chapter in the Hadid family’s story. Aydan, the daughter of real estate developer Mohamed Hadid and Terri Hatfield Dull, emerged as the third half-sister on Mohamed’s side, joining Marielle and Alana Hadid from his first marriage to Mary Butler.
Aydan’s search for her birth heritage started in Florida, where she grew up with her mother, Terri Hatfield Dull, who she regards as her role model and her best friend. As far as she had ever known, until the age of 19, her father had been a different man. When he passed away suddenly, she tested her DNA from curiosity, which revealed her connection to the Hadid family.
“After his passing, she decided to take a genetic test out of curiosity, and that’s how she discovered a biological connection to us,”
Gigi and Bella stated. This discovery, which occurred around 2021, set the stage for a life-changing reunion.
Aydan crossed paths with Gigi and Bella in Paris near the end of 2023 while studying abroad.
“We first met Aydan at the end of 2023, and he quickly became a part of the family,”
the sisters said in their statement. Since then, Aydan has hung out with the Hadid family, including their father Mohamed Hadid, although their relationship remains in the “building” stages. Earlier this year, Mohamed did not even show up at Aydan’s graduation from Parsons School of Design in May 2025, an indication of stepmom-induced acceptance.
Aydan is making her name in the fashion world – she just graduated from the prestigious Parsons School of Design in New York City in May 2025. Her candid Instagram post,
“WTF………. I graduated college,”
captured her excitement and vibrant personality. As a designer, stylist, and influencer, Aydan showcases her creative work on her Instagram account, @toospoiled. Her professional endeavors align with the Hadid family’s fashion legacy, yet she remains focused on building her career independently. The Hadid family has emphasized their desire for Aydan’s privacy, requesting that the public respect her wish for anonymity as she navigates her new reality in New York.
The announcement has generated significant buzz on social media, with fans expressing both surprise and curiosity. Some have humorously remarked on the term “unveil” used in media coverage, likening it to a product launch. For example, an X post by @melvinnasasira quipped,
“This rollout feels like they soft-launched a sibling the way brands tease a new product”
These lighthearted reactions highlight the public’s fascination with the Hadid family’s story.
Aydan becomes part of a modern family home that includes Gigi (30) and Bella (28) as well as their brother Anwar (25), and their half-sisters Marielle (44) and Alana (39) from Mohamed’s first marriage. An image of Mohamed, the Palestinian-American real estate developer was born in Nazareth in 1948.In 1994 Mohamed married Yolanda Hadid, whom he divorced in 2000, the same year Gigi, Bella and Anwar were born. A short relationship with Terri Hatfield Dull ensued after his divorce, and Aydan was born September of 2001.
The Hadid family’s high fashion and entertainment profile have helped shine a spotlight on Aydan’s story, but they have consistently said she must have her privacy. “They wanted to keep this piece of news quiet for Aydan, for the sake of her privacy,” an insider shared with Us Weekly, noting the family’s protective stance in the matter.
