I had a conv with a pal about this last week and he made an excellent point. See when she was in the diary room just before getting chucked, BB was talking to her about her 'gangster' threats. At no point did BB mention the name of ANY other housemate, but Alex said that she was talking to Darnell and Mo, not Rex.
I haven�t really seen BB but I watched a few of their introduction video thingys and they are all so artificial!! Properly because normal people wouldn�t want to go in to that horrendous house!!
