Radio listeners often have a very fertile imagination when it comes to body shape.

I cannot step into any day without help. I have a fantastically engaged husband who is very present for his children and our family life. We've got a brilliant nanny, other help from parents-in-law, godparents, friends. Also, I've had incredible women around me in the business.
