Mick Jagger has become a great-grandfather. His granddaughter Assisi, who is 21, reportedly gave birth to a baby girl this weekend.

It’s a double celebration for the Jaggers, as Assisi’s mother Jade is also pregnant and due her baby this month. The mother and daughter celebrated their pregnancies together in March, throwing a joint baby shower.

Earlier this year, 70-year-old Mick was left devastated after the death of his partner L'Wren Scott.  The Rolling Stones front-man and the fashion designer had been in a relationship since 2001.
