Housemates to face surprise eviction

Big Brother is to surprise the housemates with a live eviction just minutes after they have completed their latest task.

The celebrities will be set a challenge to produce a film about their time in the house, but just as they settle down to watch the final cut, presenter Davina McCall will inform them that the public has already voted out one of the nominated celebrities.

Whoever is chosen will then have to pack their bags and leave the house immediately.

Michelle and Ulrika recently speculated about leaving the house prior to the final, with Ulrika commenting that she thinks she will only be in the house for "one or two more nights".
