‘I actually got called to the Diary Room because one of my outfits was too revealing,’ the 25-year-old told Daily Mail Australia.

‘He [Big Brother] said it’s a family-friendly show and that I had to change it to something else, and I feel kind of proud of that too,’ she laughed.

Charlotte said that despite getting a warning from Big Brother, she kept up her rebellious antics and didn’t adjust her wardrobe.

‘I guess it’s very different to the Big Brother of the old days, so that’s kind of an achievement. Who gets told off for that?’ she added.

The Melburnian was sent packing on Tuesday’s episode after she was voted out by the other housemates.

Charlotte said she felt ‘betrayed’ by Ari Kimber but was glad she ‘played a very open game’.
