I think people hate any celebrity who thinks they're better than anybody else - and she does come across a bit like that. A bit I'm so perfect with my life, my cookery (really?) my perfect lifestyle - she's a bit Anthea Turner who's also hated for being Little Miss Perfect.
I don't really get it why people would hate her that much - she's pretty harmless!
If she admitted to having a chocolate binge or came across a bit less perfect maybe people wouldn't vote this way.
We like our celebs to have flaws - or at least appear human once in a while.
