When Assisi’s first daughter (pictured here in a photo shared on Instagram) was born, she said she didn’t think her grandfather would be referred to as “great-grandpa” anytime soon. Assisi herself doesn’t even refer to him as her grandfather. “I call him Mick—I wouldn’t start calling him grandpa,” she told Hello! in 2014. “I imagine it’s nice to be a great-grandad. Although I’m not sure he likes the idea of getting old or being called one.” According to Daily Mail, Assisi also told Hello! that when she called Mick to tell him she was pregnant, he responded, “Well done,” to which Assisi said, “I didn’t have to try too hard.” While his reaction may sound stolid to some, Jade told Harper’s Bazaar in 2015 that her father “loves babies.” “He’ll go out in the garden and play hide-and-seek or read to them,” she said. “And he’s learned how to give really good pep talks and be really supportive about their education.” Jade was 20 when Assisi was born and Assisi was 21 years old when she had Ezra (pictured here with Romy in another photo shared by their father on Instagram). “The women in our family just tend to have children young. It runs in the genes,” Assisi told Hello! “I grew up quite quickly and wouldn’t have considered having a child if I was doing what my friends are doing at this stage, messing around. … I don’t drink, I don’t smoke, and I’m very settled.“ae0fcc31ae342fd3a1346ebb1f342fcb Jade was confident that her daughter would be a great mom before Ezra was born. “She’ll be a perfect mum,” she told Hello! “Assisi is a level-headed, sweet girl, and I think it will give them both a lot of pleasure. It gives you an amazing purpose in life, to fulfill nature’s destiny.” Although Jade was confident Assisi would excel as a mom, she was still a bit anxious. “Like any mother, I was worried for Assisi, but I couldn’t ever feel that she was too young, as I’d had her when I was even younger,” Jade told Harper’s Bazaar. However, her confidence in Assisi overshadowed any doubt. “She could see that I knew she’d be great,” said Jade.

Jade gave birth to Ray Fillary just a month after her daughter had Ezra. The mother-daughter duo was able to share the experience of pregnancy and motherhood in a unique way. Assisi told Harper’s Bazaar that she has a “special bond with Ray,” her brother, who’s younger than her daughter Ezra. “Ezra feels like my daughter who just isn’t living with me,” Jade added. “When you have your own child at the same time, it’s harder to think in terms of generations.” RELATED: See Bob Dylan’s Grandson, Who Is a Major Model.
