Charlotte Crosby has let slip about a secret WhatsApp group chat which contains her and several other Australian celebrities.

The Geordie Shore star, 33, said on Thursday she is part of a private chat which includes her co-stars from the 2020 season of I'm A Celebrity Australia.

Called 'Brob', Charlotte said the group includes the likes of Rhonda Burchmore, Miguel Maestre, Tanya Hennessy and Dilruk Jayasinha, reported news.com.au.

'It's' called "Brob", because when we were in the jungle [on I'm A Celeb], there's all the monkeys and we constantly felt like they were [making noises like that],' she said.

'The only time the chat reignites is every time there's a new season on, we all go, "Oh, they're not as good as us."'

She continued: 'There's a big slack-athon in the group chat about how ours was better and we were better.'

Charlotte appeared on I'm A Celeb Australia back in 2020 and struck up a short-lived romance with media personality Ryan Gallagher.

She also grew close with other castmates, and flew back Down Under for a personal reunion with Tanya, 38, and Miguel, 44, after the show wrapped in South Africa.

At one point she even welcomed Dilruk, 39, onto her podcast Values And Vibrators to catch up and reminisce on their time in the jungle together.

It comes after Charlotte confirmed earlier this week that an Australian spin-off of her smash hit reality TV series Geordie Shore was in the works.

Charlotte featured in 12 seasons of the UK show from 2011 - 2023 as it followed the daily lives of a group of single young men and women living in England. 

After quitting the series last year following a row with co-star Marnie Simpson, she told Kyle and Jackie O she will join the franchise spin-off 'Aussie Shore' as the 'boss'.

Also appearing on The Project on Wednesday, Charlotte said Aussie Shore will be a shock to viewers due to its hard-partying storylines.

'A lot has changed in seven years, and crazy back then is nothing like crazy now. This generation is wild,' she began.

'Everyone thinks Geordie Shore was the wildest show on TV, but it has nothing on Aussie Shore.'
