I don't get why people think it's so outrageous that the HMs talk about each other - what other news can they talk about in there?
Their home life? - BB would blank it all so we couldn't hear it anyway
Housework? - limited interest here
Tasks? - again, a limited scope
Each other? - a constantly renewable topic
The real bitches are the ones that run around telling everyone else what has been said in other conversations.
Not that anybody's name springs to mind at the moment ...
