Helen Wood and Nikki Grahame confirmed to enter tonight

Helen Wood and Nikki Grahame will be two of the housemates going into Big Brother for this week’s huge Time Warp twist.

Last year’s controversial winner will join Big Brother 7‘s Nikki Grahame in the Secret Lair, but the identity of the third ‘legendary’ housemate going in has not yet been revealed.

The trio of familiar faces will be joined by either Marc O’Neill, Sam Kay or Simon Gross, who will be the subject of a fake eviction tonight.

They will then live in the Secret Lair until Sunday night, when all four of them will return to the main house for a Time Warp week of twists and turns.

Channel 5 has promised that the week will see “a succession of time travelling twists, classic tasks and a roll call of Big Brother famous faces from the past”.
