Big Brother Season 27, titled A Summer of Mystery, premieres July 10 at 8 p.m. ET on CBS. Set in the eerie Hotel Mystère, the new season promises suspense, secret guests, and surprise twists—plus a disruptive masked visitor.

New episodes of Big Brother Season 27 air live on CBS. If you don’t have cable, you can watch Big Brother online with a live TV streaming service (such as DirecTV or Fubo) or with a subscription to CBS’s streaming service, Paramount+. See below for pricing and free trial details for each of these options.

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.

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.

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.
