Voodoo Child, who is the tubby one that is always sat next that woman called Mrs. Lawson on BBBM, has posted this on Digital Spy...
"I have now heard from a respected source and read on Alex Sibley's facebook that the plans are now for five BB housemates, and five Celebs. Hence why Pete and Alex are no longer taking part.
A friend of Alex has commented saying Nadia has apparently failed the psych tests.
All this of course now if UBB goes ahead though this news has made me less excited."
