The couple tied the knot in a lavish ceremony at the luxurious Aynhoe Park hotel in the Cotswolds, England in July 2012.
The arrival of Assisi's baby girl last month made Jade's father, Sir Mick Jagger, a great-grandfather for the first time, and Assisi previously insisted he was thrilled about her pregnancy.
She said: "He said, 'Well done,' and I said, 'I didn't have to try too hard.' "
But she added: "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."
Jade's new son is The Rolling Stones rocker's fifth grandchild.
