While Shiraz didn't directly name Paule in the post, it is clear after the online feed this week that it is about her boyfriend's baby mama.
She continued: "I suppose that's the only thing you know because that's how you got your followers in the first place.
"I can't relate because you and I are on two different wavelengths."
"I have no respect for people who use others during their difficult times to promote themselves," the 30-year-old reality star wrote.
"People taking advantage of a situation and making the father of my child look bad.
"And to be pathetic enough to write and appear like you wish us both well. All of this to promote yourself and to gain followers.
"You know who you are, you know what you set up and arranged. I would say your name and tag you but you're that irrelevant to me … Oops look at that, I've already forgotten your name."
Cyrell was recently pictured breaking down in public over the split and the rumours that Eden was seeing Nicole.
Hours after the couple had called time on their whirlwind romance, Eden — who rose to fame after starring as a contestant on Love Island— was spotted grabbing a drink and getting cosy with Australian Instagram model, Nicole.
As per the Daily Mail, Eden was in high spirits "as he laughed and joked" with the brunette who was dressed up in a skin-tight white angel costume for a themed basketball game in Sydney.
On Friday, the reality star took to her Instagram 24 hours later to share the upsetting news while she cradled her baby bump.
