Josie Cunningham, who rose to fame after having a boob job on the NHS, attacked Katie yesterday in several tweets, writing: 'Babe, you've got it all wrong - I've never looked up to you as a career role model, just as a hard working mother.'

'I wouldn't copy you for a career, I mean - having @danebowers toe up my v***** and then leaking it as a sex tape isn't my kind of thing.'
She added: 'Truth is, like most of the country - I find Emily MacDonagh a real role model. She's well educated with class.'
Josie was responding to comments Katie made in her weekly magazine column, in which she said the young mum was 'absolutely disgusting' and famous 'for all the wrong reasons.'
Katie tweeted this afternoon a cryptic: 'ha ha ha that's funny,' although it's unclear exactly what she was referring to.
Could Katie be responding to Josie's claims?
