The Essex reality star will make a late arrival in the Australian jungle alongside Made In Chelsea's Spencer Matthews and Ex on the Beach's Vicky Pattison.
Speaking on I'm A Celebrity… Get Me Out Of Here NOW! before entering, Ferne said: "I feel like I have a massive point to prove because everyone thinks I'm a bitch and mouthy and gobby.
"To be fair, I am mouthy and gobby and straight talking and opinionated but it's not in a malicious nasty way. I never ever take myself too seriously and I'm always up for having a laugh."
Ferne also shared her thoughts on the Bushtucker Trials, saying she'll do her best each time.
"You can come back with ten stars or two stars just as long as you've given it your best shot. I will give everything a go."
I'm A Celebrity continues at 9pm on ITV.
