Talking to New! magazine, the 29-year-old Girls Aloud star 'fessed up to being broody, and admits she totally understands WHY most celebs decide to have elective c-sections rather than a natural birth.
Kimberley also claims that she will be something of a pushover as a mummy - leaving all the telling off to her partner, Justin!
It was her baby nephew's arrival that really made Kim start thinking about pregnancy and birth.
She says: 'I was already broody but I was at the birth and that put me off. My initial thoughts were, 'Whoa, no chance!' But I see how amazing my nephew is and it's all worth it.'
And it was WATCHING him come into the world that made her re-think those baby delivery options: 'I feel people should have a natural birth but I'm not going to lie – after seeing it, I can see why most celebs opt for a caesarean. I would want to at least try and give birth naturally.'
Kimberley says she and musician boyfriend, Justin Scott, also 29, probably will marry - it's just all down to timing.
The couple have just moved into their dream house in Hertfordshire, and whilst Justin is busy building his career, Kimberley is about to take to the West End stage to replace pregnant Amanda Holden as Princess Fiona in Shrek - but marriage definitely seems on the cards:
'We're pretty loved-up and everything's good,' Kimberely explains. 'We're both committed enough to each other so I think it's just a matter of time. He's working on getting his own career set up and I respect him for that.'
And when those babies come along it'll be Justin taking care of the discipline because Kimberley knows just what sort of mum she'll be already:
'I'd be soft,' she admits, 'Justin will have to be the disciplinarian!'
