Rebeckah is much more than just a bitch though, she tries to manipulate everybody and stir things up like no housemate in there could do it.
Anyway, if Rebeckah leaves, Maisy could become the next bitch because she isnt receiving as much attention from the male housemates as I think she thought she would and could become bitter about it.
I honestly think Alex and Louise are innofensive, especially Alex.
Heaven is a nutter and entertaining but not a bitch.
