Regardless of it being a proper job or not, regardless of her being an over paid lacky or not she should have shut up and taken the money and done a runner at the end.
Her CV would have been the envy of the other contestants and she could have gone anywhere. As it is she has shot herself in the foot and could well be unemployable now!!!
Who wants some one that, according to the reports, didn't pull her weight AND would sue you if she wasn't happy? I wouldn't!!!
