The 'Big Brother' housemates awoke to find the garden transformed into a cemetery.

The eerie outside area contained gravestones with each of the housemate's names on, as well as a bath full of blood and various body parts - included severed hands - strewn across the lawn. Some graves had stuffed crows perching on them.

Sophie asked Siavash: "Have you seen your grave? It's got a hand on it!"

The housemates soon came to the conclusion the gravestones and other scary materials are part of this week's shopping task.

Lisa was excited, saying: "This is going to be a good, good task!"

She then launched into an off key rendition of Michael Jackson's 'Thriller' - which famously had a video featuring a group of zombies dancing in a graveyard.

Charlie moaned his gravestone wasn't in the right place.

He said: "I wish mine was in the sun."

A little later Bea and Lisa pretended to be Zombies and attack each other in the house bedroom.
