In front of 1500 home crowd fans chanting "Charne, Charne, everything's going to be OK", singer-performer Charne White was tonight the first housemate evicted from Big Brother 2012 at Dreamworld on the Gold Coast.
White, 31, had been the bookmakers' favourite as the first to go.
Her obsessive cleaning of the house resulted in her attracting 22 nomination votes from housemates compared to law student Estelle Landy's 14 and British beautician Layla Subritzky's 12.
The retro glamour girl, who works at cabaret restaurant Dracula's Queensland and suffers obsessive compulsive disorder, told host Sonia Kruger she had told her friends she would rather be the first than the last to go and that it had been hard in the house with her condition.
"I'm an oddball and I don't care," she declared, adding she had missed her mum and the chance to perform while in the house.
Subritzky attracted 49 per cent of votes to save her, Landy 27 and White 24.
A male housemate will be up for eviction on Sunday after the men failed to correctly match all female housemates to their secrets.
White's OCD was the first secret correctly guessed.
It was then revealed Angie Murray was a champion weightlifter, Landy was a high school dropout, Zoe Westgarth used to be an emo and Stacey Wren was a hand model.
As leaked during the week by the Behind Big Brother website, Subritzky is distantly related to Polish royalty and Sarah Wentworth-Perry was the nude protester, having taken part in an anti-fur protest in Sydney in 2008.
The male housemates were punished by Big Brother after WA's George Baramily and Victorian model Ryan Buckingham broke the rules by directly asking two of the female housemates about their secrets, resulting in their lifelines being reduced from four to three.
With just one lifeline left, 18-year-old Bradley Darke incorrectly picked Murray as a member of royalty.
