Gigi and Bella Hadid revealed a shocking family secret in a new statement yesterday (29 May).
After being kept under wraps for the past two decades, it turns out the model sisters also have a younger half-sister.
They shared that Aydan Nix is the result of their dad, Mohamed Hadid’s ‘brief relationship’ with a woman named Terri Hatfield Dull.

The fashion faces met the 23-year-old for the first time less than two years ago as they say they have ‘cherished this unexpected and beautiful addition to our family'.
Aydan has often been seen with Bella, 28, and Gigi, 30, since then, but it has only just now been confirmed that they are actually siblings.
It’s said that their dad’s relationship with Dull came following his divorce from their mum, Yolanda Hadid, in 2000.

The sisters told the Daily Mail that ‘while single’ Mohammed’s ‘brief relationship’ over 20 years ago led to a pregnancy.

“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,” their statement continued.
“After his passing, she decided to take a genetic test out of curiosity, and that’s how she discovered a biological connection to us. We first connected in late 2023, and from that moment on, we’ve embraced Aydan with open arms.”

The Hadid sisters added: “She’s spent time with all of us, including our dad, and we’ve cherished this unexpected and beautiful addition to our family.
“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 honour her wish and right to her anonymity as she continues her life as a young woman in New York.”

The outlet reports that Aydan recently graduated from the Parsons School of Design in Manhattan and hopes to become a designer, stylist and influencer.

The sisters also have a brother, Anwar Hadid, 25, from Mohamed and Yolanda's marriage.
The real estate developer was married to the Dutch model from 1994 to 2000. Identifying as American-Palestinian, he also has two other daughters, Alana, 39, and Marielle Hadid, 44, from his first marriage with Mary Butler. They separated in 1992.
In 2014, Mohamed was engaged to Shiva Safai, 44, who began appearing on reality show Second Wives Club in 2017. The pair reportedly split in 2019 as the 76-year-old didn't want to have children.
