The mother and daughter gave birth just one month apart – Jade welcomed her third son Ray Emmanuel Fillar four weeks after becoming a grandmother to Ezra Key.
“It was quite peculiar that the pregnancies happened at the same time,” Jade told HELLO!
“I don’t feel like a grandmother, because the babies are so close in age it almost feels like they are brother and sister.”
Jade, 42, also said the birth of the babies had brought her father, Mick Jagger, some happiness following the death of his long-time girlfriend L’Wren Scott.
“He’s been through a difficult time but it’s been great to have two new babies in the family with the joy they bring,” she said in the interview.
