Speaking proudly to OK! Magazine about the birth of her fourth child- her first with husband Kieran Hayler, 26, the new mother admits:
'Everyone who's met him comments on how he doesn't look like a baby who was eight weeks premature because he's so big! He's healthy. I was massive with my pregnancy - the biggest I've been out of all four pregnancies.'
Kieran added: 'He was 5lb 0.2oz when he was born and now he's nearly 10lbs, so he's already doubled!'
Reality star and model Jordan is also mum to 11-year-old Harvey with footballer Dwight Yorke, as well as Junior, 8, and 6-year-old Princess with first husband Peter Andre, and revealed:
'I always said Princess might be a bit funny, but they're both actually really hand-on. Princess tries to copy me, and when he cries she wants to pick him up and jiggle him about.’
And it looks like the 35-year-old isn’t ready to stop just yet.
'I've always said that I want loads of children. I don't want to grow old lonely! But Kieran has said he only wants one more, and I'm saying "I don't think so!
'For me, I'll carry on going, but with Caesareans, you can only have so many, so I'll carry on and then I joke that I'll then get a surrogate.'
Speaking about her delay in announcing Jett’s birth, Katie explained:
'Jett was born on August 12th, but no one knew that he's been born until almost a week later. We were just doing it for ourselves,and because Pete was away with the kids in Australia, I wanted to tell them myself before anyone else knew'.
She added: 'I'm insulted people could suggest Kieran should have a DNA test - we both are. It's ridiculous and not nice for Jett when he grows up. He's definitely the father - you don't even need to justify it.'
And Katie is taking a healthy approach to her post-pregnancy body.
'If I do have the odd lump and bump then so what?'
'I'm supposed to be doing the marathon for Vison Charity next April, so really I should start training for that next month. I keep saying to Kieran: "Please be strict with me." I try to eat healthily but in the evening I'm like, "F**k it, lets go and get the chocolate biscuits!"'
'But if I do have the odd lump and bump then so what? I'm entitled to after four children. I put on about three and a half, four stone during this pregnancy. I'm always 8 stone and now I weigh about 10 stone, so I've got about a stone and a half to go until I get to my normal weight. But I'm in no rush.'
