Erin McNaught and Stace Cadet are officially engaged!

The Aussie model, 43, and music producer whose real name is Stasi Kotaras, shared the wonderful news on Instagram with the help of their boys.

“Mother’s Day – 10/5/26 💍💖😭🥹🥰,” the former Miss Universe contestant captioned a loved-up snap with a sparkling diamond ring on her left hand.

“With our three beautiful boys by our sides, Stasi asked me to be his wife and I couldn’t be any happier 🥹❤️❤️❤️(I said yes, obvs 😜),” she continued.

“I love you infinitely @stacecadetmusic Beyond excited for our future adventures, whatever they may bring 💫✨🥰❤️.”

In the announcement photos, newly engaged McNaught shared an adorable look into Cadet’s touching proposal.

One photo shows three hand-made Mother’s Day cards from McNaught’s three young sons, arranged with a fresh bouquet of flowers and a kids’ white tee that reads ‘Will you marry daddy’ in stunning gold foil.

The star also shared a close-up of her sparkling engagement ring which featured an oval cut diamond and silver diamond band. 

The couple were flooded with congratulatory messages from friends and family in the comments.

“Congratulations beautiful! So happy for you both xx 💍❤️,” wrote one follower.

“Congratulations!! So happy for you,” commented two-time Olympic gold medallist Shayna Jack.

A fourth snap captured a smiling McNaught with her new fiancé, and sons Obi, Evander and Ennio.

One-year-old Obi is the youngest child of McNaught, who also shares two older children, Evander, seven, and Ennio, five, with her ex-husband, musician Example.

The wonderful news comes less than a year after McNaught shared an update on son Obi’s recovery after he underwent surgery to remove a brain tumour.

The tumour was discovered after the parents noticed a “rapid decline in Obi’s behaviour and happiness”. They revealed the diagnosis in June 2025.

In the update, the star revealed “Obi has blown us away with his recovery. Day by day, achieving more and more.”

The model and actress said whilst they “still don’t know what his future holds, but then again no one ever does”, for now they are “filled with joy, and happiness, and a deep sense of gratitude”.

“We hold him close, and we hold our big boys, and we marvel at our little family, and how lucky we are. And we love each other the hardest.”

McNaught first found fame as a model, representing Australia in the Miss Universe competition in 2006. This was followed by a successful stint on Neighbours before she moved to the MTV Hits Weekly Hot30 Countdown show.
