"I have no respect for people who use others during their difficult time to promote themselves," she wrote on Instagram. "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."
Hours after hundreds of Cyrell's fans flooded Nicole's Instagram with nasty comments, she took to social media to respond to the reality TV star's fiery attack.
"Perhaps you should face your issues like a grown woman and actually address your problems rather than placing them all on social media. You know what the real situation is here, however, instead of talking about this like adults in private you would rather play the victim because your life revolves around attention (that no one cares about).
"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."
In an attempt to get the last word, Cyrell replied to Nicole's public dig in a cryptic post.
"People who have no life will always try to start drama in yours," she wrote.
