If you think Tyson is bad then you've clearly forgotten last year's biggest villains, health-food fanatic Jess.
She was the woman who turned Australia against her when she called Manu Feildel fat and claimed 'I hate chocolate'.
However it seems her carefully manicured persona has all come crashing down now that she's no longer on the show.
Jess' Instagram profile is littered with images of fast food and sugar-filled treats.
In fact, when New Idea sat down with Jess for an interview early last year, she greeted us while eating a handful of crisps.
So who is the real Jess?
