I watching BBC live news yesterday. The initial report they had said that KP confirmed it was her. Subsequent reports then said they hadn't.
A news article I read yesterday, I think on the BBC but maybe elsewhere said that KP are in a bit of a catch 22. On the one hand, they don't want to encourage the publication of photos taken whilst they are off duty by the mainstream media, but on the other they hoped that this would shut down the batshit crazy online stuff.
Read the threads here, it hasn't.
