Davina McCall will enter the Big Brother house tonight while the housemates are present, for the first time ever.

Apart from her quick commentary to them on each eviction night, Davina never makes contact with the housemates during their time in the house. However tonight the presenter is set to spend several hours with the group, though she won’t be sleeping over.

There is of course going to be a twist. Before the double eviction show, the group will be given a task where they all have to dress up in animal costumes and are told not to speak. The first housemate will be evicted in their animal costume and Davina will then don the costume and enter the house. If all goes to plan, the celebrities won’t even be aware that Davina is in their midst.

A source told The Sun: “This is a perfect way of giving Davina a taste of house life.”
