Volatile housemate Charley Uchea has become the latest Big Brother evictee after being the bookmakers' favourite.
Charley was the bookies' hot favourite to be evicted
The unemployed 22-year-old from London went head-to-head with Tracey Banard in Friday's public vote.
Meanwhile five new contestants joined the show on Friday, staying in the Big Brother "halfway house".
Audience figures for the show are at their lowest since the series launched eight years ago, with an average of 3.7m viewers tuning in each night.
Charley, cousin of Sunderland and England footballer Kieran Richardson, looked annoyed but not surprised as her name was read out.
She recently took part in a "fake eviction" where she was ejected from the house and sent straight back in.
Since entering the TV reality show, she has been involved in highly-charged arguments with many fellow housemates.
Her most recent spat was with Brian Belo, who has emerged as favourite to win the entire series.
Bookmakers Paddy Power were offering odds of 1/100 for Charley to be evicted, compared to 14/1 for Tracey, a cleaner from Cambridgeshire.
A spokeswoman said she was one of the surest candidates for eviction in the show's recent history.
The five new contestants are a man who practises witchcraft, the former leader of a Doctor Who society, a teetotal glamour model, a posh student who has a problem with "common people" and a part-time care assistant.
The five entered the Big Brother halfway house in a specially extended live show on Friday.
Over the next two days, they will spend some time in the real house before two of them swap places with existing housemates on Monday.
Afterwards, those in the halfway house will battle against each other in an attempt to make their way back into the main house.
The current nightly viewing figure is down from 4.6m at the same point in the series last year.
But a spokesman for the Channel 4 show said a number of major long-running series, such as EastEnders and Coronation Street, had also seen their ratings drop over the same time period.
He said: "Big Brother remains Channel 4's most popular programme. It consistently beats its slot average and attracts a huge number of young, upmarket viewers.
"As homes with multichannel television have nearly doubled in five years, it's evidence of Big Brother's enduring appeal that this series is watched by an average of almost 4 million viewers - an audience that all broadcasters would be thrilled with."
