The supermodel recently commended the former couple -- who split in 2021 -- for raising such a "sweet, generous, spirted, perfect angel" in their daughter Khai Malik as co-parents.

Sharing photos of herself and Khai in honor of the little one's fourth birthday, Bella wrote on her Instagram Stories Sept. 19, "Auntie loves you more than all the birds in the sky and all of the sand on the beaches."

She added in a sweet aside, "@gigihadid x @zayn my favorite collab thank you from the bottom of my [heart emoji]."

But the love didn't stop there. Bella went on to call Khai the "best girl," sharing pictures of her niece visiting a stable, petting a horse and painting an equine figurine.

"Horse girl, artist," the 27-year-old continued. "Daughter of the year."

However, Khai's interests reaches beyond just horses. As Gigi noted in a birthday tribute of her own, "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."
