Married at First Sight's Cyrell Paule and Love Island's Eden Dally have broken up.

Married at First Sight‘s Cyrell Paule and Love Island‘s Eden Dally have split, four months before she is due to give birth to their son.

The reality TV star, who is currently 23-weeks pregnant, announced the breakup via Instagram on Friday night.

“Even if it’s just you and me. We’ll create our own happiness,” Cyrell, 30, said alongside a selfie of her in underwear, holding her growing pregnant belly.

Cyrell and Eden, 26, had been together for seven months, and their child is due in February next year.

Cyrell also posted to her Instagram Stories on Friday night, writing: “You would think people would be happy to hear about my break up. Are you all not happy. Was this not what you all rooted and prayed for. Or maybe your prayers of me having a miscarriage is what ur hoping for next.

“We live in a sad, bad world where [we] wish and pray for misery on others to feel better about ourselves.

“I hope this shows a reflection of the weak, sad individual you are. I may not have a partner. But my son is all I need.”

Since the beginning, the public speculated that their relationship was a publicity stunt to remain relevant in the public eye, which they both have firmly denied.

"I wouldn’t be surprised if my child is going to get called a publicity stunt," Cyrell told New Idea in August when she announced her pregnancy.

"I guarantee people will say the baby is a publicity stunt," Eden added. "They’ll say we got pregnant to stay relevant or to extend our 15 minutes of fame. It’s very stressful and stress can cause bad things to happen."

Cyrell and Eden have unfollowed each other, and Cyrell has deleted all photos of the pair on her Instagram profile. Eden is yet to publicly comment on the breakup.

Cyrell was on this year's season of Channel Nine's Married at First Sight, when she matched with electrician Nic Jovanovic. The pair parted ways on good terms while filming.
