Bella Hadid is expressing the "joy" she feels being an aunt to her precious niece!

The supermodel, 25, talked about sister Gigi Hadid's daughter Khai while chatting with Daily Pop on E! on Wednesday, calling her niece "the biggest gift".

"I want to be with the baby and I want to wake up early and be there," Bella said of 13-month-old Khai, whom Gigi shares with her partner Zayn Malik.

"I never knew that I could have this much joy in my life. She's the biggest gift. Our family has changed in the best way for the better," Bella went on.

"Are there full-time aunties out there?" she added, joking that she could just hang with Khai all the time.
