Madeline Holtznagel reveals her huge baby bump in plunging sheer dress at lavish baby shower ahead of the arrival of her first child with billionaire pub baron Justin Hemmes By MARY MRAD FOR DAILY MAIL AUSTRALIA Published: 00:13, 30 April 2025 | Updated: 00:13, 30 April 2025 e-mail View comments Advertisement Madeline Holtznagel showed off her huge baby bump in a revealing dress ahead of the arrival of her first child with billionaire pub baron Justin Hemmes. The expecting mother, 28, shared a video to Instagram on Tuesday which captured several heartwarming moments from her lavish baby shower. The model revealed her growing baby bump in a $620 white designer chiffon maxi dress with a plunging neckline from Arcina Ori at the party.
Madeline couldn't wipe the smile off her face as she celebrated her pregnancy with her closest family and friends including her sister Simone Holtznagel . She let her blonde tresses fall in loose waves and opted for a very minimal makeup look. The baby shower was held at the stunning $100million Vaucluse mansion Madeline shares with her hospitality entrepreneur boyfriend Justin, 52.
Madeline Holtznagel showed off her huge baby bump in a revealing dress ahead of the arrival of her first child with billionaire pub baron Justin Hemmes Guests enjoyed an unobstructed view of Sydney Harbour up close, with blue and white balloons strewn around the Victorian rustic gothic style estate. The Hermitage was originally built in 1831 and snapped up by Justin's parents John and Merivale Hemmes for $500,000 in the 1970s. Justin grew up in the gothic-style mansion, which is now worth an eye-watering $100million, and moved back into the property in 2011 to complete an extensive renovation on the heritage-listed home.
Inside, baby shower guests took in the Carrara marble, copper fittings, natural stone and European oak joinery of the luxury mansion, which is now set to become Justin and Madeline's family home. Model Julia Cavanagh, Montana Cox, and 'nude artist' Dina Broadhurst were among those in attendance. The soon-to-be trio will spend their days languishing in an outdoor angular swimming pool complete with pool-side bar and lounge area which make the most of spectacular harbour views.
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.

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.

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.
