Welcoming a new addition into his growing family, Mick Jagger became a great-grandfather over the weekend.

The Rolling Stones rocker's 21-year-old granddaughter Assisi Jackson gave birth to a baby girl.

This is the first child for Jackson and her boyfriend Alex Kay. It is also the first great grandchild for Mick.

While chatting with Hello! Magazine, Assisi's mother Jade Jagger opened up about giving birth to her daughter when she was 20 years old. “The women in our family just tend to have children young, it runs in the genes."

“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,” she added. “I don’t drink, I don’t smoke and I’m very settled.”
