Why a day task and not a weekly task?
I can't see them failing the modelling task and not getting the party.
The split shows tomorrow would be just highlights but with another HM going in we would have a reason to watch the second show. (They could have a little teaser at the end of the first show)

A possibilty I think....

I think Nikki looked lots better with the blonde bob.

Imogen doesn't suit blonde though.

Unlikely. Davina would have hinted towards something on Friday (she only said they would be getting punished).

doubt it, more likely they would have a new housemate enter in a live show

As has been explained it is split due to Gordon Ramseys new series starting and the finale of Desperate housewives.

Yes thanks for that. I've only been told that 300 times now. All people can say for sure is that the programme discription say "highlights of the last 24 hours in the BB house". So, if a new HM went in tonight it would be in tomorrow's highlights, hence the programme discription.
