Davina McCall will tonight become a Celebrity Big Brother housemate for the first time. The show's host has been in the house many times before, but never part-way through an actual series. During tonight's shock (for the housemates, not for us) double eviction, the first housemate to get the boot will do so wearing an animal outfit as part of a task. The plan is that after whoever it is has secretly left, Davina will put on the same suit and go into the house via the Diary Room. The costume will protect her identity and housemates will be forbidden from talking to her. BB aren't revealing how long she'll be in there or even what she'll be doing, but we love the sneakiness of it. The only thing that could mess things up is if Basshunter gets the boot. Suit or no suit, Davina just isn't that tall. Who do you think will be walking the plank tonight?
