In an interview with The Times, the mother of five said: "I love babies and I was thinking, how can I get one quick? I know it's hard to adopt, so I thought, can't I just buy one abroad? Do you know where you go?"
The interviewer said 'no' and pointed out rather than saying "buy a baby", perhaps she should use the phrase, "rescuing them from orphanages."
Katie replied: "But that takes ages, doesn't it?"
Katie, 38, has often spoken about her desire to have more children. She's already mum to sons Harvey, 14, Junior, eleven, and Jett, three, and daughters Princess, nine, and Bunny, two.
Speaking on Loose Women back in September, she spoke about wanting to adopt a newborn baby, although husband Kieran Hayler is apparently eager for another biological child.
"Some people might be like: 'Well, why do you just want a newborn? Adopting a child, you're giving it a home anyway.' Number one, because I've got my kids. If I had a child of say five, six, seven - this is my opinion and not everyone will agree - if its got problems or something I don't want it to affect my kids, if that makes sense?" said Katie.
"And newborns... I just love to mother, nurture, I'd want a newborn so it grows up with us. We've got five kids, all these animals, what difference is another kid?"
"[Kieran] would adopt but he's like, 'Why would you adopt when you can still have your own?'" she added ."I said to him, 'I've always wanted to adopt.' I've got 11 bedrooms and they need to be filled. I don't mean that jokingly. There's so much love in our house anyway. I wouldn't do it if I didn't feel I could offer the love and support all my kids have."
