Following the removal of two contestants from the house and many arguments, there is speculation that the current series of 'Big Brother' may be taken off the air before it is scheduled to end.
A report in today's Daily Star quotes a source as saying: "This lot are out of control. There's a real fear the show will not make it to the end of its run."
Over the weekend Rebecca was warned over her "aggressive behaviour" following an argument with Darnell.
Some bookies have also suspended bets on a housemate quitting the show.
A spokesman for Ladbrokes said: "We think it's only a matter of time before one of the inmates calls it quits."
The bookies' decision follows Rex's announcement that he was willing to leave.
He told Mohamed, Rachel, Kathreya and Darnell: "If something doesn't change soon, something big, I can't take it any more. I'm just not bothered any more."
The latest developments follow the removal of Dennis from the house on Friday for spitting on Mohammed; the previous week Alexandra was removed from the house for her behaviour.
Kathreya is currently the 10/11 favourite to win the show, if it continues.
