The always outspoken Katie spoke about surgical regrets on today's Loose Women, saying she looks "shocking, ugly and not even attractive" in some photos from her past.
"There have been times when I had my lips so big I looked like Daffy Duck," she said. "I've been there, tried it, looked awful. I have calmed it down now although I still have Botox."
When a photo of a younger Katie flashed up on screen, she cringed: "It's so bad! Look how bad that is. What was I thinking? It's just vile. I honestly did a big circle. When I started Page Three years ago, to have your boobs done was a massive thing. Now, 25 years on, it's becoming the norm to have things done."
"There were a lot of people around me that were yes people, but my mum would say, 'What are you doing to yourself?' I look back and think, 'Shocking, ugly, not even attractive.'"
She added: "I've been so lucky it all disappeared."
