Last night's show proved how fake the whole thing is.... They made a big deal of Katrina and Amie being MIA whilst the tradies were doing all the work. Katrina apparently went shoe shopping and Amie was getting her hair done.
The true story was this: The room was so full of people at the particular moment they filmed, that the girls couldn't get in there anyway. Katrina went shopping for work shoes to wear whilst doing the messy reno jobs, as her existing pair had been ruined during the water challenge (or something ). Amie wasn't getting her hair done at all - that scene at the hairdressers was shot weeks later.
There was a previous episode where the voiceover went "while everyone else was working, the girls have gone shopping". The footage showed them shopping alright, but for furniture and fittings for the room they were working on!
Don't believe anything you see....
