The former glamour model, who has spent over £500,000 on cosmetic procedures, said that she sometimes questions her enhanced appearance.
Katie, who was known throughout the nineties as Jordan, has had several breast enhancements, rhinoplasty, a silhouette facelift, Brazillian Bum Lift, veneers, lip fillers and Botox.
She had her first boob job in 1998 when she was just 17 and went from a 32B cup to a 32C.
Just one year later she had her second and third boob job, boosting her bra size to a D cup and then to an F cup.
Last year she had her “biggest ever” breast enhancement, which was her 13th.
She admitted that she wanted to have the “biggest in Britain” and she told OK! Magazine that she “wanted them to look fake and didn’t like the natural look”.
Sitting down with Elizabeth Day on her How To Fail podcast, Katie said: “It’s like going shopping for me, which is so bad, but I could go further, sometimes I do look in the mirror and think ‘oh are people looking at me because you look plastic or is it because you look good’.”
Katie, who has two daughters – Princess, 16 and Bunny, 9, wants to warn young women against going under the knife.
“There’s nothing worse than when these young girls now, and I will say it, in their early twenties, who are all getting fillers, all getting lips, all getting the boobs,” she said.
“I’m not a hypocrite, but I didn’t start doing my face until I was in my forties. Yes, I had a boob job, but I didn’t even have fillers.”
Katie said that she didn’t have Botox until she was around 27 years old, but admitted that she “looked like a duck”.
She thinks that her constant trips to the clinic have put her children off cosmetic surgery.
“All the girls look the same now, and I think ‘what are they going to look like then when they’re my age’? Like, I say to my kids, because they’re like, ‘oh mum, you’re not doing surgery again are you’?
“And I’m like, ‘oh, it’s alright’. They’re so used to it I think I’ve put them off for life.”
She was concerned that many young men and women having surgery don’t realise the amount of pain and recovery involved.
“You only see before and after, you don’t see in between. So I would like to educate people about it. It’s damaging to your body.”
