WATCH: How times have changed - MAFS Martha and Cyrell get into an on-screen catfight
In messages to her 189,000 followers, the Kardashian lookalike took to Instagram stories to blast 28-year-old Nic for pretending to be something he's not.
"Nic why don't you tell us how you really feel!!!" the Melbourne-born makeup artist began.
"Take some responsibility..... we out here copping all the heat and you're still trying to play the nice guy," she wrote, adding a face palm emoji.
Martha continued her rant by explaining she doesn't leak information to the media while seemingly insinuating that her co-star Nic does.
Things became even more tense when Martha posted a screenshot of direct messages between her and Nic in which she accused the cancer survivor of strategically deleting parts of the conversation.
Despite their previous animosity, Martha told one publication she was on Cyrell's side when it comes to her marriage to Nic.
"I think Cyrell was hurt because she actually did really try with Nic.
"She was really investing in it and just really wanted Nic to have her back.
"Even with the fight that we had, me and Cyrell, when she was saying, 'Nic, Martha's husband as by her side and Jess' husband was by her side - you weren't by my side?', I felt like, 'You know what, she's right'," the brunette bombshell revealed.
