EMILY Atack was forced to give up stripping off for lads magazines after "things started drooping down a bit".
The 31-year-old told how her stint on I'm A Celebrity gave her a "whole new lease of life" in her career after growing tired of being sexualised.
"For years I was known as 'Charlotte Big Jugs from The Inbetweeners'," Emily told The Jonathan Ross Show.
"That was fun, but I got to a point where things start drooping down a bit.
"I needed a new medium to say the things I wanted to say.
"I thought by doing the jungle it would show a little bit more who I am as a person. It's very easy to be categorised when you do lads' mags and all that kind of stuff…
"I thought for years people have been talking about my body, my sexuality, what I look like.
"My career became very much about what I looked like, so I thought, what better way - when the jungle came knocking - to show what I have as a person and what more I have to offer."
Emily will appear on The Jonathan Ross Show for the first time tomorrow night.
She told fans: "Still wondering if this was a crazy cheese dream but I’m thrilled to say that I’ll be making my first appearance on The Jonathan Ross Show on Thursday’s Christmas Eve special!
"I’ve played this moment in my head for about 20 years, and I don’t think I’ll ever forget walking down those little steps.
"Get a Bailey’s and join us before Santa comes!!! Christmas Eve, ITV1 at 10pm."
Emily was runner up on I'm A Celebrity 2018, losing out to Harry Redknapp,
She was announced as a new team captain on Celebrity Juice in September alongside Laura Whitmore.
