The 43-year-old, is mother to Harvey (19) Junior (16), Princess (14), Jett (eight) and seven year old Bunny.
Appearing on Netmums' Sweat, Snot & Tears podcast, she spoke about the rude comments Bunny gets from her school peers.
“Bunny at school, she gets comments from other kids. There was a time when I was wearing wigs, because I'm trying to grow my hair as I was getting bald patches from stress and stuff,” Katie explained.
"I remember Bunny saying, 'Mum, some of the kids at school say, Why does your mum wear wigs? And she's got fake boobs'.
"She's only, like, seven."
“It's a unique job that I do, so it's not a normal conversation kids would usually have with their friends,” Katie added.
"Jett says, 'Mum, my friends always say, why's your mum famous? What does she do?'”
"They ask me these questions, whereas Junior and Princess are at the age where they know everything, because they've lived and breathed it.”
Katie admitted that it can be tough on her children and sometimes she just doesn’t know what to say to them.
“What do you say? My job isn't like any other parents' out there."
When asked if she thought any of her children would get into showbiz, she said her eldest two will.
"Jett and Bunny won't, but Junior and Princess will. Junior has just signed his record deal. His album and single are going to be out soon,” she said.
"Princess one million per cent will. She loves all her YouTube stuff and, the thing is, that is the way forward. It's so different from when I started."
Speaking about what her children are up to at the moment, Katie revealed that Junior is currently working on his music career.
“With Junior he’s non-existent at the minute. Out and about, founding a new life.”
Meanwhile, Princess she says “is a mini-me” and the pair enjoy getting their nails done together.
“Princess, on the other hand, everyday… she tells me about her school, I mean, me and her, our relationship is different because she's definitely a mini-me.”
“Hair, make-up… although her dad doesn't like her wearing make-up and that, I’m the household that does, and she can explore and be like that teenager.”
She also spoke about her son Harvey, who is currently at college, and shared that he is loving it.
“What I love about Harvey is, he’ll always be a big baby. You know what it's like when your kids get older, they get to the age where they’re like ‘mum, don’t walk next to me cos my friends will see’, ‘don’t embarrass me’, I go through that with the other kids.”
Katie co-parents Junior and Princess with her ex-husband Peter Andre, and Jett and Bunny with ex Kieran Hayler.
Katie’s eldest son was fathered by ex-footballer Dwight Yorke.
On the podcast, Katie said she “hates” her children’s fathers.
"Forget it, I will stop you there. I hate the dads. The Priory no1. and The Priory no2. That’s all I’m saying.”
"My relationships with them are non-existent,” she said.
"I’m blocked from one of the dads, and it was always lawyers, lawyers. And now I refuse to do lawyers, lawyers, but luckily they’re old enough and I can talk to them direct. So one dad, there's absolutely no contact because he tries to control me all the time, and the other dad, I can’t bear him, but we talk for the kids. "
"I’m telling people here now, never ever use your kids as a pawn. If you hate the other parent, don’t let the kids know and just do what’s best for the kids.”
"You want a happy home when they are with you and a happy home when they go to them. Don’t argue in front of them.”
