Sir Mick Jagger has become a great grandfather, signalling four living generations of Jaggers. Assissi Jagger, the granddaughter of Mick, has given birth to a baby girl, according to Hello! Daily News.

Assissi is the 21-year-old daughter of Jade Jagger, 42. Jade is also pregnant and expecting a baby boy next month, which will make Mick's grandson younger than his great granddaughter. 

"The women in our family just tend to have children young, it runs in the genes," Assisi said in a recent interview.

"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."

Jade was six months pregnant alongside Assissi, who announced her own pregnancy back in November. 

Sir Mick, who has seven children to four women and four grandchildren, spent last week in rehearsals with his Stones bandmates ahead of their performance in Norway on May 26. It will be the first time the group has been on-stage since cancelling their Australian and New Zealand tour following the tragic death of L'Wren Scott. The 49-year-old fashion designer, who had been in a relationship with Sir Mick since 2001, was found hanged at her New York office in March.

Pictures of Assisi's daughter remain closely guarded at the moment, as she's reportedly signed a lucrative deal with a society magazine for a photo-shot. She currently lives in Cornwall with her chef boyfriend Alex Key.
