It's a Reality TV show, where a group of people are put into a house and live under the glare of TV cameras and microphones.
They can be watched 24 hours a day on the web sleeping, eating, and even going to the loo! Whether that gets onto our TV screens is a different matter!
Each week one housemate is voted out of the house. Housemates nominate two people for eviction and the two with the most votes are then put to a public vote.
The last person remaining in the house is the winner and gets their mitts on £70,000!
