The former Celebrity Big Brother winner told Daily Mail Australia that filming the MTV reality show isn't all fun and games, and has a less glamorous side that viewers don't get to see – especially when abroad.
'You're travelling around different islands and that is the worst possible thing to do when you're filming because you just don't get any sleep and it's always disgustingly messy and stinks. I can't think of anything worse," she said.
Charlotte added of stresses while filming the main MTV show in Newcastle: "It's not because it isn't enjoyable, but you don't have any freedom, the filming days are long, you're constantly tired, and you have to hand over your mobile phone."
The 26-year-old was an original castmember on Geordie Shore but quit at the start of June, saying she didn't want to film with ex-boyfriend and co-star Gaz Beadle anymore.
Everyone else is now filming series 13, which has so far touched down in Majorca and Ibiza.
There had been rumours Charlotte could return for cameo and special appearances, but she said on Twitter: "I appreciate all the optimistic articles of me returning to @mtvgeordieshore for "Special Occasions" But sadly there's no truth in these...
"I am no longer a part of Geordie shore and have no plans in returning. It's massively devastating for me and I will miss them all. But I'm ready and MASSIVELY excited for my real life to start now. Just to clear that up from the articles that have been claiming otherwise."
She is, however, working with MTV on new ideas, saying in an interview with MTV.co.uk: "I'm massively excited for the future and - don't worry - this isn't the last you'll see of me on MTV. I'm working on a great new idea with the team there and will always be one of the 'family'."
And a producer for Geordie Shore added: "We're working with Charlotte on other new and exciting projects, and she knows the door is open for her to return to Geordie Shore when she's ready."
Series 13 is currently filming in Spain.
