Madeline Holtznagel’s Lavish Baby Shower: Designer Dress, Bespoke Catering & $100M Harbor View Ahead of First Child with Billionaire Pub Baron Justin Hemmes

Madeline Holtznagel Hosts Lavish Baby Shower at $100M Sydney Mansion

Madeline Holtznagel, 28, celebrated her upcoming motherhood with a luxurious baby shower at her $100 million Vaucluse mansion, shared with billionaire partner Justin Hemmes, 52. The Sydney socialite, expecting her first child, welcomed high-profile guests to the historic estate, dubbed “The Hermitage,” which boasts panoramic harbor views and opulent interiors.

A-List Affair
Guests included Madeline’s sister, model Simone Holtznagel, artist Dina Broadhurst, and Merivale Group executives. Attendees shared glimpses of the event on Instagram, showcasing Madeline glowing in a $620 white chiffon gown from Arcina Ori, her baby bump accentuated by loose blonde waves and minimal makeup. The mansion was adorned with blue-and-white balloons, a gourmet spread by Merivale chefs, and a towering chocolate cake.

Decadent Details
The menu featured caviar, seared salmon, cream-filled donuts, and a bespoke three-tier cake. A gift table overflowed with presents, including a toy car for “Baby H,” as the couple’s child has been nicknamed. Guests like model Montana Cox captured Madeline laughing against the harbor backdrop, while Merivale’s design director, Nasim Köerting, highlighted the estate’s Carrara marble and oak finishes.

Historic Home
The Hemmes family purchased the Gothic-style mansion in the 1970s for $500,000. Justin, CEO of Merivale (a hospitality empire with 80+ venues), renovated the heritage property in 2011, adding a poolside bar and lounge. The estate will now serve as the family home for Madeline, Justin, and their newborn.

Love and Legacy
The couple, who began dating in 2019, have kept their relationship private but sparked engagement rumors in 2023 when Madeline wore a diamond ring. Justin, father to two daughters from a previous relationship, shares a net worth of $1.39 billion. Madeline’s sister, Simone, welcomed her own daughter in 2023.
