Model Madeline Holtznagel defies expectations by showcasing her remarkable strength as she performs an unexpected party trick

She regularly attends Pilates classes and is known to frequent exclusive gyms in Sydney’s eastern suburbs.

And model Madeleine Holtznagel, 27, proved she’s more than a pretty face as she demonstrated her impressive upper body strength while attending a backyard party on Sunday.

The girlfriend of billionaire pub baron Justin Hemmes, 50, took to Instagram Stories with a video of herself climbing the rope of a swing that was hanging from a tree. 

Other guests watched from the ground as Madeleine performed the impressive stunt in a cream crop top and matching cargo pants. 

She completed her look with a pair of trendy sunglasses and went barefoot so she could properly cling to the knotted rope.

‘Holtznagel Challenge,’ she cheekily captioned the video, adding a crying/laughing emoji. 

It comes weeks after Madeleine celebrated her 27th birthday party with a lavish bash at Justin’s $100million home in Vaucluse, Sydney.

Following the festivities, Madeline revealed on Instagram that her beau had also bought her two llamas as a tribute of his love.

Madeline shared snaps of herself meeting the adorably fluffy farm animals.

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

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

The bling appeared to be a pretty turquoise dress ring she teamed with her outfit.  

Another photo saw her wearing a different ring on the same finger as she posed in front of a bathroom mirror for a selfie.
