Gigi Hadid and Zayn Malik have kept much of their daughter Khai's life out of the spotlight, but in a touching surprise on her fourth birthday, doting mum Gigi revealed Khai's full name for the very first time. Fans were thrilled when the 29-year-old model, who shares her only daughter with singer Zayn, shared the unknown detail in a heartfelt birthday post. In a series of images, one of them showed a screenshot of a Descendants -themed scroll that had "Khai Malik" emblazoned across it.

Fans of the former One Direction star, who parted ways from Gigi in 2021, were quick to react, with one writing: "'KHAI MALIK' STOP IM SOBBING." Another said: "'Khai Malik' she's so lucky!!" A third post read: "Khai Malik, Our girl, dusk till dawn..

. I am really feeling something." While Gigi and Zayn, 31, have always been fiercely protective of Khai's privacy, both parents marked her 4th birthday with a series of heartwarming images – still protecting her identity.

In the caption, the supermodel gushed: "Our girl is 4 today and we celebrated all week!!! She loves animals (fantastical ones too), music, baby yoda, all things nature & bugs, Descendants, anything squishy or miniature, and if possible - will be in the water from dawn til dusk. "She is curious, adventurous, loving, and oh so witty. Khai- it is my life's greatest joy and pride to be your mama!!!! Thank you for the four best years of my life- you remind me to live life to the fullest every day, in the most simple & beautiful ways.
