The 31-year-old singer Zayn Malik and his former partner Gigi Hadid welcomed daughter Khai together four years ago and Zayn admitted he "wouldn’t be the man I am today" without her.
In a special Instagram tribute to mark Khai's fourth birthday, Zayn wrote: "Happy birthday to the most important person in my life, I love you more than words allow me to express, beyond proud to call you my daughter.. grateful for every second I get to spend next to you, as you become the incredible person I know you already are. Four years ago today my life changed forever and I wouldn’t be the man I am today without you."
Zayn also posted a picture of himself and Khai on a beach to accompany the sweet message.

Earlier this year, Zayn revealed he and Khai love watching cartoons together.
He told NYLON: "I actually cried at a cartoon, I don’t know if it's familiar with people. It's called Bluey. It’s for kids. It makes me cry regularly. I don't know why."
