Justin Hemmes model girlfriend Madeline Holtznagel shows off her VERY expensive taste as she sports $12.5K designer outfit while out with baby Jaeger

She may be a busy new mother to six-month-old Jaeger, but you won’t find Madeline Holtznagel getting around in Kmart sweats and Ugg boots.

The girlfriend of billionaire Merivale baron Justin Hemmes has showcased her very glamorous style in a recent TikTok video, flaunting an outfit worth over $12,500 as she spends time with her son in Sydney’s CBD. 

The clip, which was uploaded by street style TikToker StylSpot, shows the 28-year-old cuddling up to Jaeger at Merivale’s Jam Bar on George Street, when the interviewer suddenly spots her from a distance.

‘There’s this girl in front of me outside Jam Bar, and she looks like she has a really nice dress, it’s got like an animal print on it. And she’s a mum – she’s got a really cute baby,’ the man enthusiastically tells his audience before approaching Madeline. 

The model, who just so happened to be available for an interview, beamed as she introduced herself as Hemmes’ girlfriend, before giving the interviewer a breakdown of her designer ensemble. 

She began with her dress, a puff-sleeved mini designed by Nana Jacqueline, that retails for $592.

She added to the look with a set of stylish $600 Miu Miu sunglasses, and a Malachite Diamond Ring by Cartier that retails for a whopping $10,100.
