Bride And Prejudice star Micah Downey has died aged 26.
His ex-partner Milly Johnson, who appeared on the Channel Seven reality show alongside him, took to Instagram on Tuesday to reveal the shock news.
Milly, who is pregnant with Micah's child, wrote: "It is so sad & unbelievably surreal that I am making this post 😣
"On the 28 December 2019 Micah Patrick Downey passed away. I am struggling to put into words how sad & heartbreaking this is 💔"
She added: "I just hope he is at peace wherever he is & that he will always be watching over his babies 🙏🏼 A bad, bad dream. I can't believe you're not here. Rest In Peace Micah."
Sharing a video of the former couple together on her Instagram story, Milly further expressed her sadness at Micah's death.
"I wish things could have been different," she penned. "I know deep down you wanted to change."
Micah's cause of death is currently unknown.
Tributes from the pair's former co-stars flowed soon after the announcement, including Tori Ciseau, who wrote: "We love you so much, Milly. We will always be there for you no matter what you need. Micah will be watching over you and your boys. Always remember that."
Meanwhile, James Ciseau wrote "RIP, my brother Micah. Thank you for the world's best cooking nights and introducing me to some crack up dance moves. Forever love and I'll always remember the laughs."
Milly and Micah, who also share son Julian, appeared on the most recent season of Bride and Prejudice: Forbidden Weddings as they attempted to gain support from Milly's mother for their relationship.
However, they ultimately decided to split, despite Milly being pregnant with their second child.
"Leading up to the decision I made, I felt sick, heartache, deep sadness and then I just felt numb," Milly explained on Instagram of the decision at the time.
"Breaking up with someone is awful and also a very private moment. In our case it was done with many eyes on us on national television. Not easy."
