Big Brother: reality royalty?

Egg on the faces of those who doubted Channel 5's word that it was going to get the biggest and most exciting guests on Celebrity Big Brother . "Wills and Kate in BB house," declares the front page of the Daily Star. What??? The heir to the throne and his just married wife? Amazing! What next – Pippa Middleton to guest host the Gadget Show? Alas, all is not quite what it seems. It turns out they are a pair of lookalikes – boo! – raising the possibility that every housemate on the show will be an underemployed singing telegram. We're sure that won't happen.
