Rock veteran Mick Jagger is a great-grandfather.

The Rolling Stones frontman's granddaughter Assisi has given birth to a baby girl, according to Hellomagazine.com.

No further details have been revealed. The tot is the 21 year old's first child with her chef boyfriend Alex Key.

The arrival means Assisi's mom, socialite and jewellery designer Jade Jagger, is a grandmother at 42. She is also currently expecting a child.

The pair celebrated in March with a joint baby shower.

The birth is some happy news for the Jagger clan, which was rocked following the suicide of Mick's longtime girlfriend L'Wren Scott in March.
