Well if KP didn't want to know her she's gonna hang on to what she can get.
But she's right .. Kate's Kate.
The one thing i would say about Francine is bit of a celebrity leech anyway, even outside of the whole KP/PA thing.
Or she genuinely likes Pete - Katie did appear to want friends to choose between her and Pete when they split - a sign of her insecurity I suppose - and dumped anyone who wanted to remain in contact with Pete. I have yet to read or hear anything negative about Pete from people who know him or who have met him.
