The presenters of the Channel 5 reality show revealed the news on Twitter.
Emma, 40, tweeted: “I can reveal this year’s @bbuk has TWO HOUSES. Introducing… The Others. It is far. too. much! #BBUK.”
Fans of the long-running series had suspected a twist of this nature was coming due to construction of a new Big Brother house extension.
The new set-up will give viewers the opportunity to watch all the action in both houses from the set at Elstree Studios in Borehamwood.
In previous years, Big Brother has utilised secret rooms and annexes primarily for twists such as fake evictions. However, this series will be filmed with two houses from the June 7 launch date.
Bosses of the show have promised an “unpredictable” and “ominous” new summer series.
Housemates have been warned to prepare for “paranoia and suspicion” as they discover a dark force at work which “will have a dramatic and divisive effect”.
A black and white “yin and yang” theme will accompany this 17th series.
