It's a case of like daughter, like mother for Jade Jagger - who has just announced that, along with her daughter Assisi, she is expecting a baby this year.

'Happy to announce this granny is going to become a mummy,' the designer wrote on a picture, in which she has a pronounced baby bump, posted on Instagram today. 'I'm 6 months pregnant xx double whammy this year.'

Jade, who is 42, married DJ and music producer Adrian Fillary in 2012. Her 21-year-old daughter Assisi announced last year that she was expecting her first child, with her chef boyfriend Alex Kay.

We imagine the news won't have fazed Jade's grandad Sir Mick, who was said to be delighted with Assisi's baby news.

'I think making Mick a grandfather obviously had a big impact whereas, now, making him a great-grandfather is no longer particularly fascinating,' Jade recently told The Sunday Times Style.

Another royal baby!
