It’s hard pushed to time exactly when your baby is going to be born.

But Peaches Geldof who is 24, recently had a HUGE stroke of luck when she gave birth to her second  child, wait for it,  Phaedra Bloom Forever on 24 April which is the birthday of her late mother Paula Yates.

On the coincidence, she told Hello! magazine: “It wasn’t an option. Maybe it is if you go private, but we didn’t and were given the date randomly by a consultant.

“I was pretty amazed when I read it though, and had to smile. I couldn’t help feeling mum must have had a hand in it.”

Peaches, who married musician Tom Cohen, 22, last year, is also mother to son Astala who was originally due to be born on 24 April too.

However, the date was brought forward when it was decided Peaches should have a Caesarean Section.

She said: “It’s like mum was very determined that one of her grandsons would be born on her birthday.

“There’s this kind of crazy synchronicity to it.”

The birthday of her son is a fitting tribute to Peaches’ mother who was found dead at her home in London on 17 September 2000, the birthday of Peaches’ sister Pixie.
