Benett/Getty Images -- The Who famously sang, "I hope I die before I get old."  Don't tell that to Rolling Stones frontman Mick Jagger, who's about to become -- wait for it -- a great-grandfather. Jagger's 21-year-old granddaughter, Assisi, will give birth next year, according to the U.K.'s Daily Mail newspaper. 

Assisi is the daughter of 42-year-old Jade Jagger, 70-year-old Mick's daughter with his first wife, 68-year-old former model Bianca Jagger

Mick could have lots more grand kids and great-grand kids in his future: he's got seven children in all from four relationships.
