We had a hunch that the rumours were true this morning, and we can now reveal officially that it's going to be a man-on-man battle for survival on Big Brother this Friday. Siavash stuck to his promise and refused to nominate anyone, so his votes went automatically to Charlie and Sophie. However, unfortunately for him, Lisa, Charlie, Rodrigo and David all went ahead and nominated – and they chose him and Marcus. So, it's the hairy pair facing the chop this Friday. Can Marcus survive another battle, or will Siavash succumb to the public vote? We already know who we'll be voting for, but that's only because of that hot kissing dream we had (mmmm, Siavash). Who do YOU think should go? Tell us now!
