She continued: “Sitting here writing this not actually having a clue what to expect. All I know is this is going to be crazy!
“Finally, my dreams have come true and I don’t have to photoshop my head on the English line up anymore. See you soon my jungle buddies get ready for a WILD ride,” she added.
The brunette beauty also broke the news in an official video, which appeared on the I’m A Celebrity… Get Me Out of Here! Instagram account.
In the video, Charlotte is reading a traveller's guide to South Africa – where the show is filmed – when she tells fans she might visit the country being as though she’s newly single.
“South Africa?! That was such a good trip I really gotta go back,” Charlotte said.
“Well, I'm newly single now and I've got so much free time on my hands. January 5, that sounds like a brilliant day to go.”
Charlotte and her ex-boyfriend, Love Island UK star Joshua Ritchie, 25, recently broke up after two years together.
While it remains a mystery who will be joining Charlotte and Miguel in 2020, those who are confirmed will be competing for a $100,000 cheque for their chosen charity.
I’m A Celebrity… Get Me Out of Here! season six premieres on Channel 10 on Sunday, January 5.
