In a quickly deleted social networking post, outrageous Charlotte promised to "f**k s**t up" on the show next month.
The reality telly star has already shown she's not shy on telly, having done pretty much everything Ofcom will allow on MTV's Geordie Shore.
She vowed: "I'm going to F**K s**t up in the BIG BROTHER house!" before quickly removing the message.
It was previously reported that Charlotte is set to scoop £30,000 for her stint, having said herself it'll be a "walk in the park".
"We have cameras filming us 24/7 [on Geordie Shore] so I think Big Brother will be a walk in the park," she claimed.
A spokesperson for Channel 5 did not comment on the reports.
Celebrity Big Brother 2013 will launch on Channel 5 after the current series concludes in August.
Bosses are already building their line up, with football pundit Ron Atkinson and model Sophie Anderton also rumoured alongside Geordie Charlotte.
They're set to be joined by Loose Women star Carol McGiffin, while TOWIE's Sam Faiers has also been linked to the upcoming run.
