Bella Hadid gushes about special bond with her niece Khai

Bella Hadid loves being an aunt so much she wishes she could be with her niece Khai all the time.

Speaking to Zanna Roberts Rassi for E!'s Daily Pop, the 25-year-old model expressed how much she loves sleeping over at her sister Gigi Hadid's house so she can wake up and see her niece.

"I started to sleep over because I wanted to wake up and be with the baby," Bella explained. "I never knew I could have this much joy in my life."

Gigi welcomed her daughter Khai last September with longtime partner Zayn Malik. The model opened up about how Khai is "the biggest gift" which has changed their family "in the best way for the better".

The model said she loves being an aunt to the 13-month old so much that she wished she could do it full time, joking, "Are there full-time aunties out there?"

For Khai's first birthday last month, Bella posted a series of photos on Instagram and penned a sweet note in the caption.

"Happy Birthday to the greatest gift our family has ever been blessed with.... I didn't know my heart could grow this big!!!!" she wrote. "You make me smile when I'm sad and make me cry of happiness just because ur alive. I can't wait to watch you grow into the most perfect specimen of all @gigihadid @zayn thank you for my forever best friend."
