Evicted contestant Mitchell Giles reveals how often the housemates REALLY hear Big Brother’s voice

He’s Big Brother Australia’s most recently-evicted housemate.

And now Mitchell Giles, 26, is opening up about just how often the reality TV show’s contestants hear Big Brother’s iconic voice in the house.

‘During the main days with all the challenges, he’s there but not during the late nights or days off,’ the reality TV hunk told PopSugar Australia.

The hunky FIFO worker, who entered this year’s season of Big Brother as a late intruder, said that during other times ‘someone else’ does the voice, but has ‘no idea who it is.’

Daily Mail Australia last year revealed that voice actor Chris Coucouvinis plays the booming voice that interacts with the show’s contestants. 

Meanwhile, on Wednesday Giles revealed the inspiring story behind his incredible fitness transformation.

‘I used to be a real chubby kid back in school and then got bullied heaps so I just sort of had enough of it,’ he told Daily Mail Australia.  

Mitch said that he got ‘so sick’ of what he looked like that he decided to make changes by joining a gym and watching what he was eating.

‘I would go to the gym all the time and then just got hooked, he said.

The father-of-one went on to say that after learning he would be appearing on this year’s season of the Channel Seven reality series he went on an extreme diet. 

‘It was crazy, I was in calorie deficit,’ he said. 

‘I ended up losing 10 kilos in six weeks, but just knowing that I was going to be on TV, it was enough motivation to trim right down.’ 

Big Brother continues Monday at 7.30pm on Channel Seven
