Emma Willis has tweeted a picture the Diary Room chair for the new series of Big Brother.

The new chair is round and decorated with cogs in keeping with the new series’ Timebomb theme.

The housemates who will be entering the Big Brother house tomorrow night were unveiled at the weekend and include identical twins, a former X Factor contestant and a polyamorous model.

Viewers will soon see the contestants sitting in the chair as they bare their souls to Big Brother, complaining about their fellow housemates, confessing their deepest secrets and generally having a moan.

Here are some of the past Diary Room chairs.
