Big Brother: Celebrity Hijack will feature talented young people like scientists, athletes, acrobats, and Mensa members as contestants.
In a role reversal, "showbiz types" will take on the role of Big Brother - setting tasks, maintaining control in the house, handing out punishments, and listening to housemates in the Diary Room.
The house has been given a makeover for the month-long new series.
Banksy-style stencilling and graffiti adorns the walls, and instead of the four-in-a-bed set-up of the summer, there are 12 single beds.
The Diary Room chair is a neon purple and the garden has an intimate hot tub instead of a pool.

Graffiti drawings include a monkey - an image anonymous street artist Banksy often uses - in the bedroom and a chilled out cameraman in the garden.
The bedroom walls are decorated with a British cityscape and the housemates now have a gym.
Dermot O'Leary presents the series, his last Big Brother job, and Davina McCall returns in the summer.
Channel 4 said: "The identity of the celebs taking part remains tightly under wraps, but their aim will be simple: putting their stamp on the activities in the Big Brother house and generally causing mischief."
The last series of Celebrity Big Brother caused a huge furore over the racism row.
Channel 4 decided to replace the show with Big Brother: Celebrity Hijack this year.
