She is due to give birth in a matter of weeks.
And Justin Hemmes’ partner Madeline Holtznagel appears to be enjoying her last days of air travel.
The heavily pregnant model jetted back to Sydney with the billionaire Merivale boss after they appeared to enjoy a weekend getaway.
The 28-year-old covered up her baby bump in a cream wool jumper teamed with black leggings.
Upon her arrival, she shielded her eyes with some designer sunglasses and carried a stylish Miu Miu straw beach bag and a floppy hat.
The mum-to-be showed off her pregnancy glow by going makeup free and wore her blonde locks out in a wavy style.

Following behind her was her doting partner Justin, 52, who carried several of the couple’s belongings.
He dressed in a pair of white linen pants paired with a navy shirt and tied his signature long locks back into a ponytail.
The pair appeared to be returning from somewhere warm, with Madeline wearing white sandals and Justin in a pair of Crocs on the chilly Sydney evening.
Despite Madeline being heavily pregnant, she has hardly slowed down.
Justin and Madeline recently hosted the glitzy Silver Party charity gala at the Merivale owner’s stunning Vaucluse mansion L’Hermitage.
They were joined by Tyra Banks, several socialites, local celebrities and philanthropists at the exclusive event, which supports the Sydney Children’s Hospitals Foundation.
Madeline looked radiant on the night in a strapless blue velvet gown featuring a sheer midriff that put her blossoming belly on display.
With her brunette locks styled in an elegant updo and subtle, glowing makeup, Madeline was the picture of maternal glamour.

Justin matched her sophistication in a perfectly tailored black suit, looking every bit the dashing dad-to-be.
Madeline recently admitted she is set to welcome a son and is thrilled because she wanted a ‘new journey’ with her partner, who already shares two daughters with ex-partner Kate Fowler.
‘I always thought I was going to have a boy. I knew I was going to be a boy mum,’ she said.
‘Justin has two beautiful little girls, so having a boy, it’s like a whole new journey together.
‘[The baby] is going to be his little best mate.’
She said up until now she kept details of her pregnancy private, but was ready to share her journey.
‘I keep a lot of my life private and I don’t share a lot online anyway, so [being pregnant] wasn’t really something that I was going to share online,’ she said.
‘I haven’t posted about it and it’s been nice to have some quiet time off Instagram.

‘But obviously because I am in the public eye and we do get photographed quite a lot, I think now I’m at this point in my pregnancy where it’s nice for me to be able to share some nice photos’.
Madeline also revealed she has sought advice from her older sisters Anna and fellow model Simone, who both have had children.
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 model ex-girlfriend Kate, 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.
