What happened to Justin Hemmes’ girlfriend Madeline Holtznagel?

Madeline Holtznagel has debuted a dramatic new look.

The model girlfriend of billionaire Justin Hemmes looked almost unrecognisable when she stepped out with pal Jodi Gordon at Afterpay Australian Fashion Week on Thursday.

The 24-year-old had noticeably cut her brown hair short and dyed it a striking shade of platinum blonde.

She was styled in a cream blazer, matching trousers, and a sparkly silver bra.

Madeline, who is the younger sister of Simone Holtnagel, recently raised eyebrows by deleting her Instagram account.

It’s a surprising move for the rising model, as most models in the industry use social media for exposure and to book jobs. 

Madeline has been dating the billionaire pub baron, 48, for some time and she also spent lockdown at his Vaucluse mansion last year.

She now reportedly lives in a Coogee penthouse that he owns.

The couple have been spotted out and about in Sydney several times lately, after confirming their romance.

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.

She remained tight-lipped about how long she and Justin had been dating, but hinted they’d been seeing each other for longer than report.
