‘Our relationship is stronger than ever,’ claimed Kristian when asked about the scandal.

Although Mimi and Kristian were able to work through their marital troubles, Brad and Kylie did not and quit the show midway through, and their relationship status is currently unknown.

‘The thing with the show is that everything we’ve done has happened in the past. We’ve learned from everything that we’ve been through, and we’re better for it,’ Mimi began.

‘So, when it happens, it’s happened in the past. Yeah. It doesn’t really bother me.’

She then claimed there was no tension between them and Kylie and Brad, and noted their rivals were not at the event because it was difficult for the couple to find a babysitter for their four children.

‘There’s no tension. We saw them last week and I spoke to him. Yeah. But there is nothing going on.’

Mimi said their stint on the renovation series had been a significant learning experience.

‘It took coming out of The Block to be like, “Okay, let’s reflect on our experience and  what have we learned from this”,’ Mimi said.

The couple’s bombshell admission comes after their co-stars Charlotte and Maddy appeared to confirm gossip that ‘something happened’ between two of the show’s contestants during filming.

Host Carly Portch asked the pair about online rumours concerning Mimi and Brad.

‘Look, I think all will get revealed in the next couple of weeks,’ Charlotte, 22, responded, adding: ‘I think stay tuned for that.’

Maddy, 24, added: ‘We don’t want to speak on it specifically because it’s people’s real lives at stake and we weren’t obviously there, so we don’t know full details.

‘But yeah… something happened. We’re probably not the right people to speak on it.’

Fans will be eager to see how the drama plays out after Kristian, 31, and Mimi, 28, recently confessed that appearing on the Channel Nine renovation show put a serious strain on their marriage.

The Adelaide couple confirmed to Daily Mail Australia at the Channel Nine Upfronts in Sydney on Thursday that the cheating did indeed occur. Both pictured
