Well, there's no point hanging about, is there. Particularly when you're half Irish, wha'?!
The 23-year-old socialite - who already has seven-month-old son Astala - is expecting another baby boy with her rocker husband Tom Cohen, but admitted she is nervous about becoming a mother again so soon.
Peaches - who is into her fourth month of pregnancy - told Britain's HELLO!: "Finding out I was pregnant again so soon was quite a shock. Tom was so happy. He loves being a dad so much and is brilliant with Astala, who totally adores him, so he was over the moon. I, on the other hand, did have a momentary panic and go, 'Oh my god, we're going to have a one-year-old and a one-month old! How will we cope?'" It's OK, Peaches, my sister wasn't pregnant for a month after her first child and she handled her Irish twins just fine.
In some positive news, the Geldof is planning to move out of London to raise her sons in Surrey, South East England (the footpaths must be better there), and she and Tom are delighted that Astala will have a brother to play with. And puck the head off from time to time.
She explained: "There are massive benefits to having two children so close together. Astala's such a happy, sociable little boy, I think he will adore having a sibling... As much as I would love to have a daughter one day, I am thrilled Astala will have a brother. They can share clothes and toys and do boy stuff together."
Peaches plans to name her son Phaedra, and she explained: "It's a name that comes from an ancient Greek play. But it also features in a song Tom and I both love called Some Velvet Morning by Lee Hazlewood." Phaedra will no doubt appreciate that somewhat later in life.
