Housemates who have yet to reign as Head of House will become human statues this afternoon in a bid to win the post.

Kat, Lisa, Sara, Mohamed, Rex and Nicole have all yet to take a turn leading the group.

The six must recreate the poses of famous statues and stand still in those positions for as long as possible. Whoever remains still for the longest will be crowned Head of House and be immune from nominations this week.

The group will be provided with body paint, costumes and props by Big Brother. The competitors are only permitted to wear the underwear and costumes provided for them and only those that are not competing will be permitted to apply body paint.

As Nicole read out the instructions it was decided that she and Rex would recreate Rodin's 'The Kiss', Mohamed would become Rodin's 'The Thinker' and Lisa would pose as the Statue of Liberty.

Kat and Sara will become 'Eros' and 'The Farnese Atlas' respectively.

"Well Mohamed's Head of House then," Lisa said, as she observed 'The Thinker's seemingly simple pose.

"It's not about that. It's about patience and who can stay there," Rachel assured her.
