Billionaire restaurateur Justin Hemmes, 51, and his braless model girlfriend Madeleine Holtznagel, 27, arrive at their Vaucluse mansion by seaplane after a coastal getaway.

Madeleine Holtznagel, 27, is living large as she continues her romantic relationship with billionaire bar czar Justin Hemmes, 51.

And on Monday, the model was all smiles as the couple landed by seaplane outside the restaurateur’s $100 harbor mansion in Vaucluse, Sydney.

The couple, fresh from a getaway to the New South Wales south coast, were seen disembarking from the small plane.

Madeleine was dressed comfortably and casually in a long-sleeved white dress.

The garment was light and backless, and the free-spirited model opted to go barefoot and braless.

When she got off the plane, she accessorized with a Chanel Mini Classic bag that sells for more than $8,500.

The model wore her blonde hair in a ponytail and protected her eyes from the sun with striking Miu Miu sunglasses.

Madeleine was also seen carrying a $160 oversized green corduroy tote bag from Australian fashion brand Zulu & Zephyr.

Justin, owner of the Merivale hospitality group, also looked casual in a T-shirt and shorts.

The CEO, who is worth around $1.39 billion, wore his wavy blonde hair down as he led the way from the shore to his mansion.

Madeline and Justin quietly began dating in 2019, a year after the saloonkeeper made his debut on the Financial Review Rich List with an estimated net worth of $951 million.

In June, Madeline teased her Instagram followers by wearing a ring on her ring finger while hugging Justin as they enjoyed a bowl of Udon noodles together at a restaurant in Japan.

The bling appeared to be a pretty turquoise ring that matched her outfit.

In another photo, she is seen wearing a different ring on the same finger while posing in front of the bathroom mirror for a selfie.

Earlier this year, Madeleine celebrated her 27th birthday party with a lavish bash at Justin’s sprawling estate in Vaucluse.

After the festivities, Madeline revealed on Instagram that her boyfriend had also bought her two llamas as a token of his love.

Madeline shared snaps of herself meeting the adorable, fluffy farm animals.
