Char explained in an interview with MTV, that her past history of reality TV proved a stumbling block when she wanted to go on the show back in 2013.
"Unfortunately when I wanted to go on [I'm A Celeb] they wouldn't take on anyone from Geordie Shore, and they wouldn't even interview us."
Admitting she wouldn't get to live the jungle dream, or nightmare, depending on how you feel about spiders, Charlotte decided to enter the Celebrity Big Brother house instead.
We all know what happened next - Charlotte won over the public and provided endless entertainment in the house, going on to win the whole thing. So it's safe to say her decision to go in was a good one.
However, it turns out that CBB stint three years ago put an end to Char ever jetting to Australia and chewing on Kangaroos testicles, because you just "can't" do that, apparently.
Charlotte explained: "I'm A Celebrity doesn't follow suit from Big Brother, so if you've done Big Brother you can't do I'm A Celebrity. So sadly it's a no go for me." Noo!
Reckon it's time to tear up the rule book? We'd love to see the Geordie Shore lot attempting to survive without alcohol, music or proper beds, and former cast-mate Vicky Pattison made the leap no problem... in fact, she went and won it.
