Helen Wood and Nikki Grahame have been confirmed as two of the three legendary Big Brother housemates making a return to the house.
Channel 5 bosses have announced that BB7's Nikki will join the house tonight along with last year's champ Helen.
However the third housemate, suspected to be male despite rumours it would be Gina Rio, has not been revealed yet.
Favourites in the running include BB8 winner Brian Belo and BB5 finalist Victor.
Whoever the third one turns out to be, the trio will enter the house tonight but won't join the current lot right away.
Instead, they'll enter a secret bunker for the weekend where they'll be able to spy on the main house.
And they'll be joined by one of Sam Kay, Simon Gross or Marc O'Neil who face this week's public vote after face to face nominations took place last Saturday.
None of the current housemates know that tonight's eviction is a fake with one who receives the most votes moving into the bunker with the ex-housemates.
On Sunday night (June 14) the four piece will ALL join the main house in a special live show from 9PM on Channel 5.
The former housemates will stay for the week as part of a 'Time Warp' twist that will see a number of other surprises, past tasks and familiar faces.
See the former housemates make their return and tune in to see which of the current lot joins them in the bunker when Big Brother airs tonight at 9PM on Channel 5.
