Host Emma Willis announced that viewers had voted to axe one of the housemates, revealing that it was former escort Helen who had been chosen to leave.
But in a surprising twist, Helen was then taken into a secret room where it was revealed she'd be able to spy on her former housemates (while swigging champagne.)

Wood, who once bedded Wayne Rooney, has also apparently been revealing all about her X-rated past - although most of her tales have been too raunchy to air on TV.
However arch rival Danielle McMahon, who was evicted from the house, has now gone to the press with details of Helen's sex life - in a bid to stop her winning the contest on Friday.
'She is vile. She talked about sex non-stop like it was a badge of honour. Even the lads were shocked.'

Danielle also revealed that Helen enjoyed having sex with women, as well as being a dominatrix.
'She loves anyone who talks dirty to her between the sheets too,' added the Scottish underwear model.
'Most of the experiences she spoke about were casual encounters….She is disgusting, vulgar, cheap and nasty.'
