This season, the HouseGuests have been told that there will be no twist this season and that Big Brother will be the only one watching them aside from the public. However, that is false. The main twist this season is that for the second time in the history of Big Brother, some HouseGuests will enter after the premiere. The latecomers, or Gatecrashers, will watch the remaining HouseGuests for three weeks before finding out which ones will enter the house.

HouseGuests
Advertisements revealed that sixteen HouseGuests will be moving in to the Big Brother House. It was confirmed at the premiere that five additional HouseGuests will enter the house at some point in the game. The identities of the Gatecrashers have been revealed after Amber's eviction. They have entered a secret room in the house after Natalie's eviction. Unknown to the HouseGuests, the Gatecrashers will be able to see everything they do, but not hear anything. Unknown to the Gatecrashers, the public will be voting for which Gatecrasher they would not want to see enter the house. The voting lines have opened after Cesar's eviction.
