Channel 5 has, somewhat by mistake we fear, posted a clip showing guinea pig housemates in the new Big Brother 2011 house. The 42 second teaser, featuring a pair of housemates apparently called Jimmy and Barbara having a conversation in the new Big brother living room.
The short conversation, which also quickly sees a third housemate holding their head in their hands at the new kitchen, is understood to have been uploaded as part of a test of Channel 5's new equipment in the house.
So called 'guinea pig' housemates usually spend a week or two in the new Big Brother house every year, as producers test cameras, filming equipment and the setup of the house. A number of ex-guinea pig housemates have gone one to become 'real' housemates once the series launches.
The clip shows a glimpse of the new living arena, with bright red and pink sofas, and a glimpse of the kitchen with apparently wooden-look walls.
The video also shows the garden in the background, with its extra-long pool and bridge to a "chill out" area.
We've no idea why this video has been uploaded and made public and suspect it'll be removed from Channel 5's official YouTube channel any minute, but while it's still live, check it out below...
