MARRIED At First Sight Australia star Cyrell Paule flew into a furious rage after hearing rumours another bride had "hooked up with her husband".
In a preview clip for the next episode, the fiery reality star was seen grabbing Martha Kalifatidis's bath robe as their argument got heated.
It came after Cyrell's husband Nic Jovanovic sat her down and told her: "Another rumour, but I'm involved this time."
Cyrell is then seen getting aggressive towards Martha as she shouts: "I genuinely don't like you."
Someone else in room tells Cyrell: "Get out of here, have some respect" before she is seen storming out.
And in a fight with her husband, Cyrell yells: "Don't ever sit there and say you've got my back, you've never had my back."
Unable to calm the situation down, Nic says: "So you're packing up now because of someone else?"
Cyrell is then seen walking out with her luggage.
The show voiceover says: "One little whisper leads to the biggest showdown.
"Is this the end for Cyrell and Nic?"
It's not known exactly what Nic has been accused of or whether Cyrell walks out for good.
But a sneak peek shows her being given a telling off by the matchmakers.
A stern John tells her: "You can disagree with people but you cannot get that aggressive."
