Moves like Jagger? More like movies like Jagger. The iconic rock star is practically recreating Father of the Bride Part II. His daughter and his granddaughter are pregnant at the same time!

As fans of the 1995 Steve Martin film will recall, in the Father of the Bride sequel family patriarch George Banks must accept that his little girl is becoming a mother while he and his wife are expecting a newborn of their own.

Thankfully for Mick, his situation isn’t quite as life-altering as George’s. His 42-year-old daughter Jade just announced she’s six months pregnant while Jade’s 21-year-old daughter Assisi is also expecting. That little boy or girl will be Jade’s first grandchild.

The jewelry designer shared the good tidings on her Instagram alongside a photo of her very pronounced baby bump. “Happy to announce this granny is going to become a mummy. I’m 6 months pregnant xx double whammy this year,” she wrote.

A double whammy indeed — particularly for 70-year-old Mick, who will officially be a great-grandfather once Assisi’s baby arrives. Not that he’s upset by the news. When Assisi called up her grandpa to tell him she was pregnant he said, “‘Well done,’ and I said, ‘I didn’t have to try too hard.’”

Clearly Mummy didn’t either!
