The former glamour model bitterly regrets having work done on her mouth and says she will never do so again but admitted she got carried away after being encouraged to undergo a procedure by her pals.
She said: "I`ll never have my lips done again! I know Iэve said that before but I won`t do them again. They`re not that bad and I just don`t need it but you know what it`s like when you`re there with your friends and they`re all having it done. It`s like, `Go on then. I`ll have a little shot of it as well.` It doesn`t last forever.
"At my hen do we all had Botox and fillers but they`re not permanent. I`ll try these things - as long as they`re not permanent I don`t care."
However, Katie - who has two children, Junior, five, and three-year-old Princess Tiaamii with ex-husband Peter Andre, as well as eight-year-old son Harvey from a previous relationship - isn`t worried that her kids will follow her down the cosmetically enhanced route because she doesn`t think the procedures will exist by the time they grow up.
She explained to Britain`s OK! magazine: "I think that by the time Princess, Harvey and Junior are old enough, there will be something else out there. Probably not even injections. Who knows?"
