Going back to BB5 (sorry but I really was an avid fan then). Nadia was clocked pretty quickly as a man by Victor and Jason. Most of the UK knew. It is revisionism at its finest to say Nadia passed as a woman. Nadia was massive, walked like a builder, had an adams apple and a very manly chin.
24 hour live footage was available at that time, and anyone who watched could see the manipulation of the audience. Nadia was a nasty piece of work, a bully, yet none of this was shown on the hour long programme each evening. Nadia was presented as the poor victim. BB5 was bonkers and fabulous in equal measure. Never watched again after the terrible audience manipulation. I think also it was the last series to have 24 hour live feed.
Fight night was awful, again lying to participants on your show never works out well. The obvious racism was uncomfortable. The sex under the table was awful.
