Jedward set to shake things up in 'Big Brother' house

'Big Brother' housemates face a tough task tonight - ignoring Jedward.

They have been told they are not allowed to react to any strange events going on in the house.

It means they will have to ignore Davina McCall hosting part of tonight's show from there.

They will also have to shun pop duo Jedward who will be performing their new single 'All The Small Things' in the garden.
