Emma Willis and Rylan Clark-Neal have confirmed Big Brother's new series will feature two houses for the first time.
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."
Rylan, the 27-year-old presenter of sister show Big Brother's Bit On The Side, tweeted: "A new set of Housemates will enter a new game.
"But they won't be alone. For the first time ever, Big Brother has TWO HOUSES @bbuk #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.
Big Brother's famous eye icon for this latest instalment is monochrome with colourful shards shattering off.
Last year's show was won by Doncaster office administrator Chloe Wilburn.
