GOLD Coast pin-up Charne, Melbourne skater chick Estelle and British beauty Layla are the first Big Brother housemates up for eviction.
One of the three women will be the first contestant booted off the reality series on Sunday's live elimination show filmed at Dream World on the Gold Coast.
Viewers have until Sunday to vote to save their favourite housemate via phone, SMS or Facebook.
The female housemates ended up on the chopping block after failing to correctly match the seven male housemates to their secrets in last Sunday's live show.
All 14 housemates were called up by Big Brother to nominate their least favourite roommates last night.
Charne proved to be unpopular with some of the male housemates, receiving more than half of her 22 votes from four of the guys.
Estelle was targeted by her fellow ladies, receiving 12 of her 14 votes from the women of the house.
Brisbane-based beautician Layla was the third most unpopular housemate, receiving a combined 12 votes from George, Ryan, Benjamin, Sarah and Estelle.
The seven guys also have the task this week of matching the seven girls' secrets to the correct person.
In the public domain, the cat's already out of the bag for two of the secrets.
Big Brother fans were quick to uncover evidence that Layla is related to a former monarch of Poland and that Sarah is the nude protester.
It comes after George was quickly outed as the multi-millionaire last week.
But the public knowledge will do little to help the housemates inside their media lockdown.
The pink parlour has been converted into a "man cave", where the guys will convene when prompted by Big Brother to discuss their efforts to uncover the girls' secrets.
The first Big Brother live eviction show starts at 6.30pm on Sunday on Channel 9/WIN.
