Whoah! Mick Jagger, 70, has just become a great-grandfather. Can you think of a cooler great-granddad than the iconic rock star?

The Rolling Stones‘ front man’s 21-year-old granddaughter, Assisi Jackson, has reportedly given birth to a baby girl. The child’s name has not been made public.

“The women in our family just tend to have children young, it runs in the genes,” Jagger’s granddaughter told Hello! magazine.

“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,” said Assisi. “I don’t drink, I don’t smoke and I’m very settled.”

A homeopathic business owner, Alex Key, 25, is the father, according to The Daily Mail. The couple live in a converted barn in Cornwall, about 250 miles from London.

Jagger has seven children with four women, and four grandchildren. Assisi is the daughter of Jade Jagger, 42, and onetime partner Piers Jackson.

Assisi’s mom, Jade Jagger, is the daughter of Jagger‘s first wife, Bianca Jagger, and had Assisi at age 20. Ironically, Jade is also pregnant with husband Adrian Fillary and a mother-daughter baby shower was thrown for the pair in March.

That joint baby shower was thrown right around the 50th anniversary of the Stones’ first album and was hosted by Mick’s former common-law wife, Jerry Hall.

The coolest new great-grandfather in the world may not want to be called grandpa, however.

“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,” said Assisi. “I call him Mick – I wouldn’t start calling him Grandpa.”

One would imagine this news is a bit of joy for the rock-‘n-roll legend, who suffered a great loss when his longtime love, L’Wren Scott, took her own life in March.

“I am still struggling to understand how my lover and best friend could end her life in this tragic way,” Jagger wrote on Facebook. “We spent many wonderful years together and had made a great life for ourselves.”

Congratulations to the entire, extended Jagger family.
