So that's the housemates sorted, but what's the plan for the launch?
*
-12 housemates will enter the house tonight.
-The Las Vegas theme remains but it's been revamped for the c'lebs.
-The housemates will face an immediate task as they enter and nominate after just two days of knowing each other.
-And finally...*producers are rumoured to be over the moon as their biggest star*has remained a secret. There's been no mention of this mystery housemate by the press and the CBB team are hoping to keep it that way. For once will we have a BIG showbiz surprise?

Any ideas? I've heard Jonathon Ross once or twice, but otherwise
