Mick Jagger hates being called `Great-grandpa`?

London: Rocker Mick Jagger, whose granddaughter gave birth to a baby girl, reportedly hates being called a great-grandfather.

The 70-year-old star goes into a rage if someone calls him great-grandpa, reportedly. "Mick hates it," said a source close to the star, adding, "He goes into a rage if you call him that, and then he`s in the dumps." The title apparently makes him feel ancient. His granddaughter Assisi, who turned mother in May said she is not sure Jagger would like being called a great-grandfather. "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," she said, adding, "I call him Mick, I wouldn`t start calling him `Grandpa`."
