The seven-year-old, whose dad is model Kris Smith, has just returned from an all-American adventure with his mummy.
Dannii and her little guy were seen arriving into Melbourne airport.
The Minogue queen gave us major airport fashion going for an all black ensemble featuring black jeans, black top, black hat, black shoes and a black Gucci handbag, breaking it up with a large bright red coat.
Mean while her growing son Ethan, was seen wheeling his own luggage along, wearing a denim star wars jacket and a bright yellow batman hat.
Ethan, who turned 7 earlier in July, has already grown to almost be Dannii's height, standing proudly up to his mum's shoulders.
Looking back on her pregnancy, the 45-year-old mused that she loved the experience.
"I've never loved my body more than when I was like six-seven months pregnant. You just rub the belly! I miss that, a lot. Even when I'm sleeping and I lie down, I miss that feeling of having that whole bump there," she told Kate "Monty" Diamond on Show + Tell.
