Zombies perform their 'Thriller' moves

A nervous Head of House sat in the living room watching as housemates performed Michael Jackson's iconic music video 'Thriller' this evening.

Choreographer Rex was told he must remain on the couch for the duration of the shopping task show, which was being performed in the spookily-decorated task room.

The room had taken on the appearance of a graveyard scene, complete with smoke machine and green lights. Housemates merged into the background, dressed in rags and made up to look like reanimated corpses.

Housemates bade each other "good luck" as Big Brother told them that the music was about to begin. The group then emerged from their graves and pulled scary expressions as though they were the dead.

Rex chuckled at first, but soon looked nervous as the main routine got underway.

As the final move was performed, the Head of House dashed to the task room door and shouted to his team that they had "nailed it".
