Lisa Curry and her ex-husband Grant Kenny have had to say goodbye to their eldest child Jaimi Lee Curry Kenny, 33.

The family have confirmed that she passed away following a private battle with a long-term illness, and the family have chosen not to disclose the nature of her illness.

Lisa has broken her silence and paid tribute to her "beautiful daughter" in a powerful Instagram post.

"Our hearts are completely broken. 💔So loved. So beautiful. So kind to everyone.... So painful. I can barely breathe," the 58-year-old wrote.

"Jaimi will forever be remembered as a caring, bright and loving soul who always put others before herself. Her love of flowers, cooking, art, decorating, photography, babies, the beach, and helping others will always be remembered."

"Our hearts are broken and the pain is unbearable but we cherish every wonderful moment we got to share with our treasured and so loved first child."

"We thank all the paramedics, support staff and the incredible team at the Sunshine Coast University Hospital for their tireless commitment to give us the extra time we were able to spend with Jaimi," the mother-of-three said.

"It goes without saying that this is a very difficult time for our family and all who knew and loved Jaimi so very much."

"Rest in peace my beautiful baby. I will miss you every sunrise, I will miss you when the sun is shining and the birds are singing. I will miss you when the clouds are dark and stormy and when the rainbow appears. I will miss you when I close my eyes. I will miss you when I open my eyes. I will miss our long hugs and long chats. I will miss watching, feeling and knowing your love for your sister and brother, your little nephew, Cleo, your Ma and dad😞."

The heartbreaking message was finished with disbelief that Jaimi was gone.

"I just can't believe you're not here anymore. I sit and just shake my head. It doesn't seem real or right. You will forever be with me in my heart Jaimi. I love you so much. 🌸👼💕."

Her father Grant Kenny also released a statement, thanking the "incredible team" at the Sunshine Coast University Hospital.

"Jaimi will forever be remembered as a caring, bright and loving soul who always put others before herself," Mr Kenny wrote in the statement.

"Our hearts are broken and the pain is immense but we must move forward cherishing every wonderful moment we got to share with our treasured first child.

"We thank the incredible team at the Sunshine Coast University Hospital for their tireless commitment to making her better and giving us as the extra time we were able to spend with her."

He has asked for privacy for himself and his family during this time.

"It goes without saying that this is a very difficult time for family and friends and we trust we will all be allowed to grieve in privacy," he said.
