The former glamour model – who already has sons Harvey, eight, and Junior, five, and three-year-old daughter Princess Tiaamii from previous relationships – dismissed speculation she and husband Alex Reid are expecting a child together, but admitted she wants to keep adding to her family.
She said: "Because I didn't drink on my hen night, people say I'm pregnant. They can speculate all they like but I'm not.
"It was because I was driving that I didn't drink that night.
"I want 20 children. Or course I want more children. But I'm not pregnant yet."
The 32-year-old star – who has amassed a rumoured £30 million fortune from modelling, books, fragrances, TV appearances and magazine interviews – insists she doesn't understand why she receives so much criticism and believes she is a great role model.
She added in an interview with the Daily Record newspaper: "I'm living my life how I want to live my life. I don't see why I can't be a good role model.
"I don't see what I've done that is so bad.
"People are very judgemental of what I do. I'm not perfect but who is?"
Katie and Alex, 34, recently renewed their wedding vows in a lavish ceremony after marrying a secret Las Vegas ceremony in February.
