"But when I had it done... it looked awful but it's all going down now. The thing is, it doesn't last forever which is good. But no, I still look like a chipmunk." Asked what motivates her to undergo Botox, the star said: "It's not permanent. Yeah, no it's mad, but then I blame my friends and my family because we all did it."
Katie denied she was addicted to the treatment, saying: "No, if you have the proper stuff, like I've seen some people who go too far... but the odd jab of Botox and that - it's like, everyone does it.
"It's so obvious what celebrities have had it these days, and they're like: 'Oh no, I'm natural. It's absolute rubbish," she added.
