The Block's Courtney McInnes reveals what Kylie said to Mimi after THAT cheating scandal with husband Brad

The Block's Courtney McInnes spoke out on Tuesday about the shock cheating scandal involving her co-stars Mimi Belperio and Brad Baker.

The furniture designer, 32, told HIT WA's Allan & Carly that Kylie Baker had reached out to her co-star Mimi, after the shock on-set cheating scandal which saw Mimi become involved with Kylie's husband Brad.

'They definitely have talked after. I wouldn't say they are really close right now, but they've spoken,' Courtney told the hosts. 

Courtney added the co-stars had formed a shaky friendship in the scandal's aftermath, but was unsure of how close they were.

'Everything's fine. So I don't know if this is going to resurface things. Who knows, but weeks ago, they were talking.'  

She then revealed whether both Kristian and Mimi and Kylie and Brad were still together as couples.

'Yes. They're very much still together. We saw them a couple of weeks ago for an event. We're all still friends and yeah, they're still together.'

Courtney's surprising comments follow reports that Mimi desperately tried to cover up her 'cheating' scandal with Brad just days before it aired on the Channel Nine show.

Bombshell scenes on the renovation show on Monday evening saw Brad admit to 'flirting' with his co-star Mimi.

Brad's wife Kylie suddenly quit production after overhearing her spouse telling Mimi, who is married to fellow contestant Kristian, 'you know I'd follow your OnlyFans'.

Mimi was asked about the scandal at the Channel Nine Upfronts on Thursday.

She told Daily Mail Australia she 'didn't know much' about it despite being at the centre of the incident.

'I can't tell you much about it, but I don't really know,' she said.

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

She also claimed there was 'no tension' between her, Brad and Kylie, adding: 'There is nothing going on'. 

Scenes on Monday saw Brad confess to making 'inappropriate' comments towards Mimi over a drink at his home while his sleeping wife Kylie was within earshot.

Brad later said he believed his marriage was 'done' and that he had 'single-handedly destroyed his family' with his actions after Kylie suddenly abandoned production.

A devastated Kylie flew home to Cairns to be with her and Brad's four kids after revealing how her husband had told Mimi that he would 'follow her OnlyFans'.
