What Is Big Brother Season 27 All About?
If you’re thinking this is just another season—think again. Big Brother 27 comes with a twisty theme, brand-new contestants, and a haunted hotel-style set design straight out of a movie.

- Hidden passageways
- A secret wine cellar
- A Victorian conservatory lounge
- And even a poison bar
Sounds spooky and stylish, right? But that’s just the beginning…
Meet the Cast of Big Brother Season 27
On July 10, 2025, 17 houseguests entered the game with their eyes on that sweet $750,000 grand prize.
This season’s cast is wildly diverse, including:
- A professional bull rider
- An AI consultant
- A marketing manager
- A dungeon master
- An aura painter
- An attorney
- …and surprise! Season 13 winner Rachel Reilly is back in the house as the 17th contestant.
Now that’s a twist nobody saw coming.
