I knew it!!!
I was discussing this with my DH the other day... and he said perhaps BB didn't know, perhaps it was something that she "hid" to get into the house... I knew it would have been something she wouldn't have hidden... I have recently applied for Biggest Loser 2008, and I can't remember the question exactly, but I had to tell them about Noah, so I was assuming that BB would have asked some similar questions with their applicants.

I think it is absolutley appaling the way they expected her to play this stupid little game... I never liked Kate before, but now I have a new found respect for her... she has had to deal with a lot, and thought she'd be okay to enter this "game"... I think she would have assumed they wouldn't have been so thoughtless as to make her do something like this.
The poor thing... I hope she wins now... and sticks it to BB!!!!
