Big Brother Season 27 premiered with a major twist as a surprise 17th houseguest entered the Hotel Mystère, leaving the other contestants stunned. The mystery player’s identity remains secret, but their arrival caused explosive reactions from housemates like Ava Pearl, Morgan Pope, and Zach Cornell.
Host Julie Chen Moonves teased that this unknown player is “polarizing” and will spark strong reactions. Fans are scrambling to uncover clues about who it could be, with theories ranging from past winners to controversial reality stars.
Big Brother Season 27 Premiere Introduces Mystery Houseguest
The Big Brother house was already filled with 16 contestants when an unexpected 17th player walked in during the premiere. Photos from Entertainment Weekly show the cast’s shocked faces, especially Ava Pearl, who looked like she “saw a ghost.”
“When I was told who this person is, I had to expect the unexpected!” said Julie Chen Moonves. “I never expected that person. And I was very excited because, in my opinion, getting that person is epic. And that person is also very polarizing.”
Morgan Pope, a gamer, was caught mid-reaction, swinging her arms in disbelief. Zach Cornell jumped out of his seat so fast that he was nearly cut out of the frame. Meanwhile, Vince Panaro stretched out like a basketball player, trying to block others from the cameras.
Theories About the Mystery Houseguest’s Identity
CBS has been dropping hints on social media, including a clock showing 1:16, leading fans to speculate it means “won 16.” This could point to Derrick Levasseur, the winner of Big Brother Season 16, who was a detective—fitting the season’s murder mystery theme.
Other guesses include:
- Parvati Shallow, winner of Survivor: Micronesia (Season 16)
- Johnny Bananas, a controversial Challenge star
- A political figure, given the “polarizing” description
- A past Big Brother villain like Russell Hantz
The show’s Instagram has promised more clues, keeping fans guessing until the big reveal.
How the Mystery Houseguest Changes the Game
This season’s theme, Hotel Mystère, includes multiple twists:
- A masked visitor who will “wreak havoc”
- A secret accomplice with game-changing responsibilities
- The mystery houseguest, whose role is still unknown
Chen Moonves hinted that the accomplice may fail their task, affecting the game. The masked visitor is expected to be even more disruptive than last season’s Ainsley, who caused chaos.
Cast Reactions and Fan Speculation
The houseguests had no warning about the extra player. Ashley Hollis, an attorney, was caught mid-gasp, while Keanu Soto, a dungeon master, seemed amused by the chaos.
Fans online are divided:
“If it’s Derrick, this season just got 10 times better!” – Reddit user BBFanatic
“Please don’t let it be another political figure. We watch BB to escape reality!” – Twitter user RealityLover
The mystery guest’s arrival has already made this one of the most talked-about premieres in Big Brother history.
