It's the popular renovation show that's been a ratings hit for the Nine Network.

And until now, never has host Scott Cam had to step in and reprimand a competing couple in the show's 11 seasons.

According to New Idea this week, in an upcoming episode the lovable and easy going host 'unleashes' on behalf of the cast and crew with the couple on the receiving end then threatening to walk out.

On Monday, Scott Cam revealed in an upcoming episode he 'unleashes' his temper on one of the couples

'I really unleash on one couple - in a big way,' says Scotty.

'It's a never-before-seen situation. It was actually legitimate like 'this is how it's going to go down'. It didn't get physical, but it was about my rules and what we expect.

'You could have heard a pin drop,' he continued.
