The 21-year-old and her partner Alex Beattie were booted out after a brutal last-minute secret ballot.
The public further turned on her when she and Scouse beauty Gabby fell out over a text message during a boozy lunch.
Montana has revealed to the media that the producers are the ones who made her nasty.
She told the Daily Star: “We were all encouraged to be bitchy. It was in the heat of the moment and I have been guilty of saying some things.”
As the remaining four couples prepare to battle it out for the £50,000 prize, the lovers were told to pack their bags.
Montana had previously been voted the public’s favourite girl, even though she was accused of trying to win votes with non-stop noisy sex with partner Alex.
