The TV presenter - host of Five's dating show, Farmer Wants A Wife - piled on more than two stone in both her pregnancies with five-year-old Charley and 10-month-old Beau, and while she'd love another child with husband Jamie Redknapp, she really hates "being fat".
"The thought of another pregnancy doesn't sit easily with me, I find it tough - I hated being fat, I was really sick with Charley and Beau for nine months and I felt uncomfortable carrying this extra weight around," she told the Daily Mirror.
"Afterwards was horrible too, having all this weight to lose. It made me feel very unconfident, which is why I'm not sure I could do it again. I certainly don't plan to have more children soon."
