After slamming her husband’s “inappropriate” behaviour and leaving The Block to fly home to Queensland, Kylie returned to the reality show in Wednesday night’s episode to dramatically confront Brad. The mother-of-four was left devastated when she discovered her partner, who she has been married to for seven years, had been ‘flirting’ with their co-star Mimi during backyard week.

While Kylie initially refused to interact with Brad upon her return to the construction site, with Mimi also choosing to keep her distance during a cast gathering with host Scott Cam, things came to a head later in the evening. As Mimi and her husband Kristian were filming a piece-to-camera interview outside their house, the producers captured Kylie and Brad arguing nearby.

Kylie told Brad she only returned to The Block because of the upcoming auction, but she has no plans to stay with him after filming the reality show.

“If I gave up, we’d leave with nothing, so whatever we get – even if it’s $10k – I’m taking f**king half of what you get and I’m leaving your a**. You can keep your s**t house and then I’m f**king off,” she said.

“I don’t even know if I’m staying in Cairns, to be honest. There’s nothing there for me anymore.”

Kylie went on to say that Brad has to deal with the consequences of his actions after how he has treated her.

“My biggest problem, do you want to actually know it? The entire time we have been together, and even when we were starting out, you have never flirted with me like that. In our entire relationship,” she argued. “So you can only imagine how that makes me feel.”

As Brad apologised profusely, Kylie continued: “You’ve just completely annihilated our entire relationship. So what you need to understand is just by me talking to you, it doesn’t actually mean I’m ok. Just so you know.

“This is us being separated. We’re officially single people.”

While Kylie and Brad appear to have broken up on the show, their co-stars Courtney and Grant recently shared a surprising update about their relationship. The House 2 couple confirmed during an interview with HIT WA’s Allan & Carly this week that despite rumours they’ve filed for divorce, Kylie and Brad are still together.

“I have spoken to everyone since and Mimi and Kristian are in a good place and Kylie and Brad I’ve heard are also in a good place,” Courtney said. “They’re very much still together. We saw them a couple of weeks ago for an event.”

The radio hosts then asked if there was any “tension” between Kylie and Brad at the aforementioned event, to which Courtney replied: “No, not that I knew. I’m not as close with Kylie, I guess, but we’re all still friends and yeah, they’re still together. We’re all still together!”

This comes shortly after an insider told Yahoo Lifestyle that Kylie has heavily relied on Brad’s support in recent weeks as she deals with the fallout from her ‘edit’.

“At first Kylie was laughing at the silliness of some of her antics on the show but now she has been questioning everything about herself and, surprisingly, Brad of all people has been the one to comfort her,” they shared.

“The relationship was in tatters when they left The Block but this whole experience of watching it back and only having each other as a reference point has actually been quite healing. No one really knows what happened on Phillip Island unless you were there and while many friends thought reliving some of the painful parts of their struggles would split them further apart, it has done the opposite.”
