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.
