In the video footage, Cyrell, 30, panned around and showed off the balcony of a property, which overlooked a harbour-side location - and featured an impressive pool.
Cyrell seemed to be one of the first to arrive at the BBQ, as no other guests, including Eden or his sister, featured in the video.
Speaking exclusively to New Idea, Cyrell said: “I was desperate for our son to have a mother and a father – a happy home, a happy life.”
“Now I go into this all alone. It is devastating. It is the last thing I ever wanted. Everyone thinks this was an easy decision. It really wasn’t.”
The soon-to-be mother also confessed her true feelings for Eden.
“It’s easy to break up with someone when you are no longer in love with them. It’s much harder breaking up when you are still in love with them ... I do love Eden.”
Cyrell admitted their different parenting values were a big reason behind her shock split with Eden.
“Honestly, I just think we wanted different things. I was happy to stay at home and focus on the baby whereas ... Eden still wanted to go out and do his thing,” Cyrell says.
“We were going in different directions. I wanted to see certain changes in Eden as a partner and as much as he was trying ... it wasn’t really in him.”
Cyrell revealed there are still a lot of unresolved issues between the former couple.
“Even now he is asking what are the plans for the kid? When does he get to see him? When do I have him? What happens with the things he needs?”
She says it breaks her heart that her son won’t be born into a loving two-parent family.
“I really do feel sorry for my child. He won’t get what other kids have. He won’t come home and see both the parents there,” she told New Idea.
