Big Brother returns on Thursday on a new television channel. The former Channel 4 show will now be broadcast on Channel 5, after the network agreed a deal with programme creators Endemol in April.
A celebrity version of the show is expected to last for three weeks, before the traditional version of the series - featuring members of the public - begins immediately afterwards.
Much speculation has been made about which celebrities are entering the house. It has been reported that Jedward, Amy Childs and Kerry Katona might be participating in the new series - but Channel 5 have refused to comment.
There is one bedroom this year, complete with a hairdryer and a pair of hair straighteners, which the housemates are expected to share. Producers have also included one double bed.
Former Big Brother contestant Brian Dowling, who won series two and the very final series last year, is replacing Davina McCall as the show's presenter.
Despite poor ratings in recent years on Channel 4, bosses at Channel 5 are confident the show will attract new audiences to the station.
The house has made been made more luxurious this year, with a bigger garden and swimming pool, say producers. There is also a barbecue and sauna outside.
There will be no live streaming this year, instead fans can follow updates on Facebook and Twitter.
The diary chair has become an iconic feature for the show, which started in 2000. It is always placed in the diary room, where housemates go to talk to Big Brother.
A gym, featuring a large yoga mat and various exercise machines, has been designed for the celebrity housemates.
For the first time the show will be recorded in high definition. A total of 42 cameras have been placed around the house.
