We'll have to agree to disagree on this one. If Jodie Marsh told me the sky was blue, I would go outside and check for myself. I do not believe one word that comes out of her mouth. Judging her from her behaviour, I believe she was far more likely to be the bully than the bullied.
The way she responds to any criticism does give this impression, there's a lack of self awareness that gives the impression her recall of any conflicts might be a bit 'one-sided'.
