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, reported Showbizspy.
"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'.
