Mum-to-be Madeline Holznagel showed off her burgeoning baby bump for the first time on Saturday.
It was revealed last week that Madeline, 27, is set to welcome her first child with billionaire Merivale boss Justin Hemmes, 52.
The model, 27, looked radiant when she stepped out, with Justin, to the Sydney wedding of Bernadette Fahey and Jordan Sukkar.
Madeline looked stunning in a figure-hugging rust red gown that finished just above her ankles.
The fitted, sleeveless dress flaunted her toned arms and also showed off a hint of baby bump.
It also featured a high neck and an eye-catching rose appliqué on the right shoulder.

Madeline finished her stunning ensemble with a pair of strappy black heels that featured a red floral embellishment that matched her dress perfectly.
Wearing her blonde locks back in a tight bun, Madeline added a pair of stunning diamond earrings.
She also accessorised simply, with a $3,760 black leather Fendi bag.
Justin, meanwhile was the perfect dapper accompaniment to Madeline in a classic black tuxedo and white dinner shirt.
He finished his outfit with a pair of black suede shoes with a silver chain acrross the bridge of the foot.
Madeline was also spotted doting on Justin, helping him into his jacket as they arrived at the venue.
Like his partner, Justin also wore his hair back for the occasion, while also sporting a shock of stubble.
The couple arrived late to the wedding showing up during the reception, according to onlookers.

The loved duo looked chuffed to be in each other’s company for the romantic occasion.
As they walked into the event, Justin held Madeline’s hand sweetly, before throwing his arm around her shapely waist.
Madeline is the younger sister of fellow Aussie model Simone Holtznagel, who welcomed her first child, a daughter called Gia, in March with her now-ex-boyfriend Jono Castano.
Justin and Madeline were most recently seen earlier this month, when they arrived back in Sydney after enjoying a weekend away with Justin’s two daughters.
Madeline wore an oversized T-shirt as she strolled through Sydney Airport’s private jet terminal with a huge smile on her face, just 12 days before their baby news was made public.
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.

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.
Another showed the pair cuddling up to one another as they relaxed on a yacht.
‘Happy birthday my love,’ she wrote in a caption along with rose emoji.
Earlier this year, Madeleine celebrated her 27th birthday party with a lavish bash at Justin’s sprawling Vaucluse estate.
Following the festivities, she revealed that her doting partner had bought her two llamas as a sign of his love.
The couple have gone from strength-to-strength since going public in 2019 and even sparked engagement rumours last June.
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.
Justin was previously in a relationship with Kate Fowler and the pair remain on good terms, often jetting off on holidays together with their daughters Alexa and Saachi.
