Madeline Holtznagel looked every inch the doting new mum on Thursday as she was spotted running errands with her precious new bub in Sydney.
The model, 28, and her billionaire beau Justin Hemmes, 52, welcomed their first child, Jaegar Justin on June 1.
Madeline cut a stylish figure on the windswept streets of Double Bay, as the new mum donned a slick streetwear set and matching sneakers for the outing.
The bubbly blonde was seen hitting the shops with her bundle of joy rugged up in a designer Silver Cross stroller (which can retail for between $500 and $3000).
Going casual for the afternoon stroll, Madeline wore a plain white hooded sweatshirt and a pair of matching pants.

Madeline swept her blonde locks back into a high ponytail and completed her chic ensemble with a pair of black Chanel sunglasses.
Her trim and toned pins were on full display, and she finished off her look with a pair of two-toned sneakers.
The younger sister of model Simone Holtznagel went solo for the outing and cuddled her sleeping newborn close to her chest.
She kept her accessories to a minimum, selecting a simple pair of gold hoop earrings and an oversized black leather Miu Miu bag to tote around her things.
The newborn heir to hospitality magnate Justin’s vast hospitality fortune looked very cozy as he nestled into Madeleine’s jumper hood.
Jaegar sported a light grey sweatshirt and a sleepy smile as he hit the streets of the well-heeled eastern suburbs for the very first time.
This marks his first public outing since the new family arrived home from the hospital via seaplane at Justin’s $100million Vaucluse mansion on Tuesday.
It comes after Madeline announced Jaeger’s arrival in a sweet Instagram post last week.

‘Jaeger Justin Hemmes 1.06.25,’ she captioned the post.

The sweet photo dump included an array of snaps showing the couple’s newborn baby wrapped up in a blanket.

She was positively glowing as she beamed at the camera while her precious newborn wore a smile on his face.

One adorable snap showed Justin leaning down to kiss baby Jaeger, who was tucked into his jumper to keep warm during the windy outing.
Friends and family flooded the comments section with well wishes for the couple and their new bundle of joy.

‘I love him,’ Madeline’s sister Simone Holtznagel simply wrote.
Madeline recently announced the sex of their baby in an interview with Stellar magazine, and said she was thrilled because she wanted a ‘new journey’ with Justin.
‘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 she previously 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.
In November, an insider confirmed the exciting news of Madeline’s pregnancy to Daily Mail .
They revealed a friend of Justin’s recently moved out of his Vaucluse mansion to make room for their growing family.
The business mogul, who has a net worth of $1.39billion, began dating Madeline in 2019 when she was 22 and he was 47, after his split from Fowler in 2018.
Madeline is the younger sister of Simone, who welcomed her first child, a daughter called Gia, in March 2024 with her now-ex-boyfriend Jono Castano.
