Not just a pretty face! Model Madeline Holtznagel shows off her impressive strength as she performs surprising party trick

She regularly takes Pilates classes and is known to regularly visit exclusive gyms in Sydney's eastern suburbs.

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

The girlfriend of billionaire pub baron Justin Hemmes, 50, posted a video on Instagram Stories of herself climbing the rope of a swing 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 trendy sunglasses and went barefoot so she could cling to the knotted rope.

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

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