She even revealed that she had a scare recently via her blog for Baby.co.uk, where she wrote: "I felt a sudden gush underneath and had no control or way of stopping it.
"Immediately adrenalin surged through my body and I started shaking. I thought oh my god, this is it, my waters have broken, the baby is on its way."

Thankfully, despite losing lots of water, Natasha did not go into early labour - although she has been told to slow down and relax, as she is coming closer and closer to her due date.
So it makes sense that the Atomic Kitten star has been feeling nostalgic about motherhood, sharing an adorable throwback photo of herself and eldest son Josh, shortly after she gave birth to him 12 years ago.
The image, which shows a fresh faced 22-year-old Natasha, sees the proud mum cuddling up to baby son Josh, and is captioned: "Me & Josh 12 years ago today x"
