The unfiltered admission comes just a month after her gender reveal with her partner, and MAFS alumn Jack Millar.
"What was our little secret, is now yours 🤍," the couple captioned a video of them kissing and then popping balloons to reveal the pink confetti inside.
The pink is of course referencing the fact that the lovebirds will soon be mum and dad to a beautiful baby girl, and judging from their reactions to the gender reveal, the pair couldn't be happier!
The couple took to their Instagram to share that they would soon be parents in mid-May, revealing that their bubs to be was due in November 2023.
In the video, footage was shown of the couple strolling along a beach whilst Jack gently cradled, kissed, and showed affection to Courtney's belly and the baby inside it whilst the song Love in the Dark by Adele played in the background.
The footage then panned to a small plaque in the sand that read "Baby Millar" was coming in six months' time.
"Overjoyed to share our magical secret with you," the pair captioned the post.
The reality tv stars have been dating for almost a year after they met at Jack's ex-wife from MAFS Domenica Calarco's Showpo fashion event in June 2022.
And whilst Domenica and Jack didn't work out as partners, they are still firm friends, Domenica being one of the first to congratulate the couple on their happy news.
"BEST NEWS EVER!! Congratulations you two beautiful people" Domenica wrote under their announcement post.

Fellow MAFS cast member Brent Vitiello also jumped in the comments section to share his congratulations for the couple writing, "STOP!!!!!!!! I'm going to be an uncle!" whilst Ella Ding wrote "UM OMG! This is such beautiful news, congratulations both of you!!!"
Jack and Courtney moved in together in January this year, Jack revealing at the time that he was "eternally grateful" to Courtney for making the move from her hometown of the Gold Coast.
"I am still working in finance so it was a lot harder for me to move than it was for her because she's still doing social media full time."
"So new beginnings for her and new starts for me."
