Big Brother's Isabella Farnese has been punished after revealing outside information.
It followed the results of this week's nominations being revealed to the house in Tuesday evening's episode.
Lewis Flanagan, Hussain Ahmed, Isabella Farnese and Tomasz Wania were all originally up for eviction.
Housemates nominated as usual on Sunday other than Hussain Ahmed, who secretly won the power of a killer nomination in Sunday's Big Brother auction. Hussain nominated Lewis, who is guaranteed to face the vote.
In the rest of the nominations, Hussain received 5 votes and Tomasz received three votes while Isabella was nominated by the viewers to join them.
Only new housemates Isabella and Hussain are aware of the secret viewer nominations, which have been taking place all series.
And in Tuesday's show, she accidentally let slip of its existence to the rest of the house.
"I'm just thinking who and what would... why would someone nominate me?" she reacted to the news of her nomination.
Isabella told the other housemates in the bedroom: "I think I'm really hated. I think it might have been the public poll or something."
The revelation prompted initial shock from the others, with Akeem Griffiths reacting: "What do you mean by public poll?!"
However - somehow - she got away with it by brushing off her comments as speculation.
But Big Brother wasn't as easy to fool.
Tonight (Wednesday), Big Brother issued Isabella a punishment.
"As you know, it is against the rules to discuss information from the outside world. Last night you broke this rule," Big Brother said. "It is also against the rules to discuss nominations. You also broke this rule.
"Big Brother takes rule breaks very seriously. As a result of these rule breaks, Big Brother is fining you a total of 150 Big Coins."
Isabella reacted: "But I didn't mean to.... I'm sorry and I won't do it again."
Elsewhere this week, Isabella and fellow new housemate Hussain came to blows over her closeness with Lewis.
"You roll with the opposition, you are the opposition, end of story," he told her as she accuses him of 'turning on her'.
Hussain later complained to Big Brother in the Diary Room: "Isabella's just p**sing me off. I feel as though she's playing some sort of game and it's annoying me. I think she probably thinks that I'm the big bad wolf in this whole situation."
Big Brother airs Sunday-Fridays at 10PM on Channel 5.
