Rolling Stones rocker Mick Jagger is to become a great-grandfather at the age of 70.
The musician's daughter Jade Jagger's eldest daughter Assisi is due to give birth in the new year.
It will be the first baby for the 21-year-old socialite and her partner Alex.
"She and Alex are thrilled and broke the news to their immediate families last week," a source told the Mirror. "Jade was a little taken aback at first, not least because it means she will be a grandmother by the age of 42."
"She's expecting some ribbing from her showbiz pals," the source added. "Mick is delighted and has no qualms about being a great grandfather. He's been joking about becoming a great, great, grandad and still performing!"
The baby will be the latest addition to the large Jagger clan.
Sir Mick is father to seven children aged between 14 and 42 by four women.
