Jagger's granddaughter Assisi Jagger, 21, recently gave birth to a girl, whose name has not yet been announced, Hello! magazine confirms.
"I imagine it's nice to be a great-granddad, although I'm not sure he likes the idea of getting old, or being called one," Assisi said around the time she got pregnant. "I call him Mick. I wouldn't start calling him grandpa."
The new addition offered some good news for Jagger during a devastating time since the death in March of his companion of 12 years, L'Wren Scott.
