Big Brother's Sophie aka ‘Dogface’ and Siavash will face the public vote for eviction - because they swore.
The two housemates were ordered to stop using expletives for five-and-a-half hours as a punishment for discussing nominations.
They were told they would be immediately put up for the public vote if they uttered a single swear word before 3pm.
To illustrate exactly which terms they were to try to avoid, Big Brother unloaded a barrage of expletives to the stunned pair.
The house will celebrate Big Brother's 10th series tomorrow with the surprise return of ‘Nasty’ Nick Bateman.
BB1's Bateman created headlines by writing notes which he showed to contestants to influence their voting.
On Monday he will take on his former nemesis - the assault course - and pit his fitness against a current housemate.
On the same day, a group of three ex-housemates from BB3 will take part in an egg and spoon race.
A current housemate must predict the winner to succeed in this task.
Tuesday will see BB4, BB5 and BB6 revisited, while on Wednesday, Nikki Grahame and Brian Belo will each take part in a memorable task from their year.
Kris Donnelly became the sixth person to be evicted from this year's series on Friday.
