Sleeper car bunk room: Behind a secret entrance, this train-themed bedroom straight out of a murder mystery novel contains bunkbeds for six Houseguests (the first time the BB house has had bunk beds since season one!) and a sleek Art Deco design.

Big Brother follows a group of people living together in a house outfitted with more than 100 cameras and 100 microphones, recording their every move 24 hours a day. Each week, someone will be voted out of the house, with the last remaining Houseguest receiving the grand prize of $750,000.

You can catch the Season 27 premiere of “Big Brother” on the CBS Television Network on Thursday, July 10 at 8 p.m. Fans can tune in to every “unfiltered moment” with the BIG BROTHER Live Feeds beginning Monday, July 14 at 12:30 a.m. on Paramount+ and Pluto TV.

These 16 houseguests, plus a mysterious additional player, will be moving into the famous “Big Brother” house for a summer filled with competitions, alliances and back stabbing.

It's also worth noting that when CinemaBlend spoke to Rachel back in 2021, she was eager to play Big Brother again. Fans may remember she wanted to be a part of Season 22's second All-Stars season, but was not able to play because she was pregnant at the time. Now, it would appear she's playing the game again, but for how long is anyone's guess.

The cast of "Big Brother" Season 27 has been revealed — with one "Mystery Player" set to make a surprise entrance.
