She’s the stunning Aussie model dating pub baron Justin Hemmes.
And on Tuesday, Madeline Holtznagel proved exactly why she caught the multi-millionaires eye when she showed off her incredible figure in a sleek and plunging black dress.
The 24-year-old looked sensational as she stepped out in one of her favorite frocks as she joined the likes of Martha Kalifatidis, Bella Varelis, and her sister Simone Holtznagel for the Charlotte Tilbury cruise event on Sydney Harbour.
Hello sailor! On Tuesday, Justin Hemmes’ model girlfriend Madeleine Holtznagel (left) almost had a wardrobe malfunction in a VERY daring dress as she joined other models and Instagram influencers wearing barely-there outfits for a yacht party. Pictured with sister Simone Holtznagel
Madeline, who hails from Wollongong, narrowly avoided a wardrobe malfunction at the event, with her plunging dress skimming her ample assets as she went braless.
Her gown, which she has worn before at another event, also featured a daring leg split which helped put her trim pins on full display.
Madeline finished her look with a pair of strappy black heels, a quilted Chanel shoulder bag, and her blonde locks swept into an elegant low bun.

Madeleine meanwhile, has been dating pub baron Justin Hemmes, 49, since last year.
She now reportedly lives in a Coogee penthouse that he owns.
Madeline lifted the lid on their relationship in October last year, telling The Sydney Morning Herald she was yet to introduce Justin to her parents.
‘My parents and my sister Anna haven’t met him yet, but [her other sister] Simone has been introduced to him and really liked him,’ she said.
Madeline remained tight-lipped about how long she and Justin had been dating but hinted they’d been seeing each other for longer than reports suggested.
