The former Spice Girl would love to add to her family - she already has sons Brooklyn, nine, Romeo, six and three-year-old Cruz with husband David Beckham - but insists she is too busy at the moment to start trying.
She said: "We would like another child but it won't be for a couple of years yet. I'm not even trying to get pregnant at the moment. I don't want another baby for two years because I'm working so hard on my fashion business. I haven't got time."
