In an extra show this Wednesday, housemates came face to face with who they had nominated.

The awkwardness started when Big Brother announced to the housemates that they had to write out their choices for nominations.

Sara received five votes and Lisa four meaning they will face the pubic vote on Friday.

The housemates' excitement about being allowed to discuss nominations was cut short when Lisa and Sara were called to the task room to perform a 'prisoners dilemma'.

The girls were given two blocks, one with 'Share' written on it and the other with 'Take' written on it.

If they both picked 'Share' they would each receive £25,000. Both choosing 'Take' would mean winning nothing but if one person chose 'Take' they would receive the whole £50,000.  

As the housemates watched in awe, Lisa and Sara decided to share the money. Both will now receive £25,000 which will not affect the £100,000 prize money.
