Fifi Box pulled out of her popular radio show on Tuesday morning following the tragic news her daughter's half-sister, Jaimi Lee Curry Kenny.
Fifi shares seven-year-old daughter Trixie with Jaimi's father Grant Kenny, a former Ironman, who confirmed his oldest daughter's death in a shattering statement on September 14.
Confirming the shocking news, he said: "It is with a very heavy heart that Lisa and I confirm that our beautiful daughter Jaimi has lost her battle with a long-term illness and passed away peacefully in hospital this morning in the company of loving family."
He added that Jaimi would be forever remembered as "a caring, bright and loving soul who always put others before herself."
Over the years, Jaimi was often pictured spending time with her half-sister and Fifi in their hometown of Melbourne. It's also believed she helped Fifi out with babysitting duties.
While the extent of her relationship with Fifi is not clear, there's no doubt the radio host would have been shocked to learn the devastating news.
During her usual morning radio show on Fox 101.9, Fifi's co-hosts Brendan Fevola and Byron Cooke told listeners: "Well Fi is away today but the show must go on."
"We're a team, we're one and one, we're going to mould into one and just nail it...If we're in the Titanic, I've got my arms around you, I'll carry you bro," Fevola said.
Fifi has not yet shared a statement in the aftermath of the devastating news, though members of Jaimi's family have taken to Instagram to share their grief and tributes for the vibrant 33-year-old.
Her younger brother Jett Kenny shared a beautiful tribute to his sister on Tuesday morning, writing: "I may not have been the best brother to you all the time, I know you thought you weren't being the big sister I needed all the time, but I do know we loved one another unconditionally all the time."
He finished: "I will love you forever. Rest In Peace my beautiful big sister, the world lost one of its treasures yesterday but heaven gained one. You will be dearly missed by all whose lives you touched."
Former Olympian Lisa Curry also shared an emotional tribute to her daughter, writing: "Our hearts are completely broken. 💔So loved. So beautiful. So kind to everyone.... So painful. I can barely breathe."
"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."
