Madeline Holtznagel is awaiting the birth of her first child.
The model, who is expecting a baby with her billionaire boyfriend Justin Hemmes, 52, stepped out in Sydney on Wednesday with her bump on show.
The 27-year-old showed off her blossoming belly in a cropped white dress shirt and a pair of jeans.
She had on a natural makeup look with a pink lip stain and pulled her blonde hair back in a ponytail.
Madeline added to her look a pair of leather sandals and carried a quilted designer shoulder bag.
In November an insider confirmed the exciting news of Madeline’s pregnancy to Daily Mail Australia and revealed a friend of Justin’s recently moved out of his Vaucluse mansion to make room for their growing family.

Justin, who has a net worth of $1.39billion, already has daughters Alexa and Saachi with his ex-girlfriend Kate Fowler, from whom he separated in 2018.
The business mogul then began dating Madeline the following year, when the model was 22 and he was 47.
They have been spotted out together in recent months looking as loved-up as ever, recently attending Pilates queen Bernadette Fahey’s wedding to Jordan Sukkar.
Justin and Madeline quietly began seeing each other in 2019, a year after his debut on the Financial Review Rich List with an estimated net worth of $951million – which has since risen to $1.39billion.
Though they generally keep their romance under wraps, the couple are often seen disembarking from his sea plane after enjoying luxurious family holidays with his two daughters.
The couple have gone from strength-to-strength since going public and even sparked engagement rumours in June 2023.
Eagle-eyed fans noticed Madeline was wearing a ring on her wedding finger as they questioned whether Justin had popped the question.
A picture showed her sporting the jewellery as she cuddled up to Justin while enjoying a bowl of Udon noodles together at a restaurant in Japan.

But the bling appeared to be an emerald and diamond promise ring, and another photograph showed her wearing a different ring on the same finger as she posed for a selfie.
In August, Madeline also made a rare public post about Justin as she took to Instagram to mark his 52nd birthday.
She shared a series of romantic selfies of them both and gushed over her partner in the caption.
In one picture, Madeline flashed a huge smile as she sat on Justin’s lap while he lovingly gazed at her.
Justin is considered Australia’s hospitality king, with more than 80 venues and billions in assets with names like the Ivy, Queen Chow and Establishment under his purview as CEO of Merivale.
He is the only son of Merivale Group founder and nightclub mogul John Hemmes and Justin took over the business after his father’s death in 2015.
Madeline is the younger sister of fellow Aussie model Simone Holtznagel, who welcomed her first child, a daughter called Gia, in March last year, with her now-ex-boyfriend Jono Castano.
