Her billionaire pub baron beau threw her a surprise birthday party for her over the weekend.
And Madeline Holtznagel was back to the grind this week, working hard in the gym.
Madeline, 27, showed off her model figure in a $170 onesie by The Upside as she attended a Pilates session at Body By Berner in North Bondi.
She also rocked a pair of Chanel sneakers and chic black sunglasses.
The younger sister of fellow model Simone Holtznagel was makeup free and had her blonde hair half up, half down for the stretchy session.
Madeline recently celebrated her 27th birthday alongside family and friends, thrown by her beau Justin.

She began the joyful day arriving via boat to the waterfront property, where she discovered all her friends waiting to surprise her.
Sharing a video to Instagram of the moment they jumped out to wish her a happy birthday, Madeline wrote: ‘The best surprise ever.
‘Thank you to my amazing boyfriend and friends who made my birthday so special.’
Madeline was surprised as she arrived at Hemmes’ home in her gym gear.
She threw her arms around Justin, 50, and thanked him, before getting glammed up in a dress more fitting for the birthday girl.

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.
The couple were all smiles in the photos, looking happy in love.
The pair have been dating for several years now. She even spent lockdown at his Vaucluse mansion in 2020.
As guests sat down at the luncheon, pub baron Justin also took the opportunity to say a toast to his beautiful girlfriend of three years
She now reportedly lives in a Coogee penthouse he owns.
While they used to prefer to keep things low-key, the couple are now fixtures of Sydney’s social scene.
Madeline recently wished her publican boyfriend a happy 50th birthday, telling Justin she ‘adores’ him in an Instagram post.
She shared a gallery of nine photos from the pair’s exotic travels across the world, including days at the beach, journeys on private jets, and camping in the woods.
Justin made his debut on the Australian Financial Review’s annual Rich List in 2018, with an estimated net worth of $951million.
Last year, his net worth grew to $1.2billion, making him the 97th richest person in Australia.
