Rebecca is the favourite currently to get the chop, with odds of 8/13 at Paddy Power. Ashleigh can be backed at 6/5.
Luke A is the outsider with odds of 12/1 to leave, while Deana is the long shot, rated at 33/1 to exit the show this evening.
There is the possibility that a second housemate could be evicted tonight, with 'White Room' task finalists Luke Scrase and Conor McIntyre being offered £50,000 - half the show's prize money - to leave the compound for good.
