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

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.

On July 8, the network shared the 16 houseguests who are ready to compete, form alliances and possibly stab each other in the back when the show returns for Season 27. Among the cast are a gamer, bridal consultant, AI consultant and aura painter who are all hoping to outlast the rest and win the grand prize of $750,000.
