Before the season 27 premiere, many fans speculated that the mystery houseguest could be anyone from Celebrity Big Brother UK star JoJo Siwa to a Big Brother newcomer like Tom Sandoval from Vanderpump Rules. Viewers even hypothesized that this season, the host herself, Julie Chen Moonves, would join the cast as a contestant.

The cast of "Big Brother" Season 27 has been revealed — with one "Mystery Player" set to make a surprise entrance.
The new season of the hit reality competition series "Big Brother" includes new elements including the introduction of a mysterious masked visitor with a secret accomplice and an unknown houseguest to be revealed sometime during the season.
Not even The Masked Singer fandom is that good at figuring out identities that quickly, so props to the Big Brother fans who figured all of this out with so little information in less than a day. CBS may want to uses masks next time.
