We all know by now, that reality TV is not always what it seems. When Big Brother candidates coming out of the diary room, saying they were told by producers to act in a certain way, it tells me that show is not reality.
Everyone also knows that if the house has houseguests that get along well, it is ratings suicide. That is why producers brought Rachel back last season to stir things up, since the remaining houseguests were getting along so well.
It seems like shows like Keeping Up With the Kardashians are produced in a way to create the ultimate drama.
