The model and reality TV star was chatting to OK! magazine when she was asked about having babies with her new beau.
'Oh definitely! Some little chicos,' she replied. 'We're not making any plans. It's early days for us.'
She also defended her decision to bring Leandro home to meet her children, Harvey, nine, Junior, five and Princess Tiaamii, three, just days after meeting him.
'I'm not going to introduce my kids to just any man. We've been very careful with them,' she said. 'Although it's happened fast, it's been a gradual thing with them. Since I split from Pete, this is only the second relationship I've had - it's not like I've gone around sleeping with loads of men.'
Katie also added she was looking forward to her children meeting Leandro's three year old daughter, Sofia, soon:
'It would be lovely for them to meet.'
Do you think Katie should have waited longer to introduce her new boyfriend to her children? Or is it best to do it early on?
