Gigi Hadid and Bella Hadid introduce their secret half-sister Aydan Nix

Supermodel sisters Gigi Hadid and Bella Hadid have recently introduced a new family member to their fans. The Hadid sisters revealed that they have a 23-year-old half sister named Aydan Nix.

During a recent interview with the Daily Mail, Gigi and Bella recalled how they initially connected with Aydan and expressed excitement about meeting their sister.
They met their half sister for the first time in 2023 after Aydan took a DNA test out of curiosity after the sudden passing of the man she believed to be her father.

The Hadid sisters revealed that Aydan is the daughter of their mother’s ex, Mohamed Hadid and Terri Hatfield Dull. Aydan was born after Mohamed's short-lived relationship with Terri, following his 2001 divorce from Yolanda Hadid, the mother of Gigi and Bella.
Aydan grew up in Florida and was unaware of her connection to Hadid.

However, they shared, “We’ve cherished this unexpected and beautiful addition to our family.” Gigi and Bella also shared that Aydan has since spent quality time with them and their extended family, including their father, Mohamed.
