Gigi and Bella Hadid had good reasons for waiting to introduce the world to their half-sister Ayden Nix.

“Bella, Gigi and Anwar have met Ayden and have been in touch with her for about a year and a half now,” a source exclusively tells Us Weekly. “They have welcomed her with open arms and are fully embracing her as their sibling.”

The insider notes that it was a “complete shock to the whole family” to learn they had a relation to Nix, 23. While the Hadids have gotten to know Nix for the past year, they wanted to wait before introducing her to the public.

“They kept this news a secret for the sake of Ayden’s privacy,” the source explains. “The Hadid sisters and Anwar have tried to not pass judgment about the situation.”

“Over 20 years ago, our dad, while single, had a brief relationship that 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,” Gigi and Bella said in a statement to the Daily Mail. “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.”
