This week's nominations revealed?

Noirin and Karly will face the public vote this week, rumours suggest.

According to website Big Brother Online, the pair received the most nominations from their fellow housemates. It is the first time either of them has faced eviction.

The duo will be joined by Sophie and Siavash after they were punished for discussing nominations.

Big Brother informed them that they could avoid the public vote if they refrained from swearing for a certain period of time, but they both failed to complete the challenge.

The nominations will be confirmed on Big Brother's Little Brother this evening.
