A new housemate is to enter the Big Brother house in a special live show tonight, and will join the remaining five of Anthony, Craig, Derek, Eugene and Makosi, after Orlaith walked on Saturday morning.

Clearly Big Brother needed six housemates still in the house so near to the end so as they could go ahead with whatever they've got planned for the remaining weeks, of which there are now less than two.

Housemates were already commenting yesterday how "this week's task has been cancelled" due to Orlaith's departure, which would hint at it having been something needing six housemates and not possible with only five. Maybe once the new housemate joins them it'll be able to get underway.

It'd seem fairly likely that the housemate who enters will be female, simply because Makosi is the only girl left in the house, and the Big Brother website has been making quite a thing of how it's very boy-ish in there at the moment with far too much tostesterone.

One possibly housemate is Kinga, who only made it as far as being a contestant for the week in the secret garden, before being given the boot by Makosi. Her entering the house would mean that she'd instantly get on with Eugene and Makosi (although maybe not seeing as she missed out on a place because of her, and because of the "childish" comment that was given as the reason for why she shouldn't be allowed in) and would also be a familiar face with the viewers, as opposed to someone that is totally unknown.

The housemate who enters possibly stands quite a good chance of being there on the final night seeing as the series is just under two weeks from the end, although they can be nominated for eviction by their fellow housemates, so maybe their stay will be very short.

Find out who enters, and the reaction of the other housemates, tonight at 9pm Live on Channel 4.
