In a lengthy caption, alongside a video with her little girl, she explained to her fans that she's expecting a baby via IVF and an anonymous donor, and revealed that she's filled with 'pure joy' over the 'miracle'.
"A few years ago I made an appointment to see an IVF specialist, the amazing Dr Sameer Jatkar at Monash IVF, and I began an IVF journey to extend our little family. After a series of egg retrievals and freezing, last year I started the process to become pregnant via an anonymous donor," she began.
"I am still pinching myself that I have been this blessed and that this little miracle is growing within me, a much wanted and longed for sibling for a very excited big sister! I know the value of this miracle because I have seen first hand the heartbreak, tears and sacrifices so many women and couples suffer on their IVF journeys and my heart goes out to those who are facing that pain and struggle," the Fox FM host continued.
Before she confessed that this new addition will be welcomed into her family with open arms, despite the journey it takes to get there.
"It is not lost on me that I am one of the lucky ones. Being a mum is my greatest joy in life, it is quite simply everything to me. Trixie has brought me more happiness and love than I ever imagined possible and to feel my heart expanding to include this little angel kicking and rollicking within me, I am overwhelmed with how much love and happiness the future holds. I will cherish Trixie and this little angel forever, and hold them so close for the rest of our lives 💕💕💕 #family"
