Yes, that's right. Rolling Stones frontman Mick Jagger is officially a great-grandfather!

Daily Mail reports that the 70-year-old rocker's granddaughter, Assisi Jackson, gave birth to a baby girl over the weekend. As of May 19, the baby's name has not been released.

Mick has seven children and four grandchildren. According to Daily Mail, the newborn's grandmother, Jade Jagger, is due to give birth to her third child in the next few weeks.

"The women in our family just tend to have children young, it runs in the genes," Assisi told Hello! magazine.

But will the Rolling Stones rocker take on the title of "great-grandpa"?

"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," Assisi adds.

The joyful baby news follows a personal tragedy Mick experienced earlier this year, when his longtime love L'Wren Scott was found dead in her apartment back in March.
