Simone Holtznagel sizzles in a hot tub with PT friend Jono Castano

Simone Holtznagel already misses the sun and sand in Bali.

The 29-year-old model and influencer posted to Instagram a gallery of throwback snaps from her trip to Indonesia’s party island last month with boyfriend Jono Castano.

She showed off her recent 10kg weight loss in a row of patterned bikinis as she and Jono lounged at their luxury abode at The Mulia Resort and Villas.

“Bali MEMS we’ve seen it all,” she wrote in the caption.

All of the photos had the same amusing theme: Simone smiled and snapped a selfie while her boyfriend slept next to her.

Her trip abroad comes after Simone debuted her body transformation in August.

With the help of her boyfriend, who oversaw her regular workouts and helped plan a balanced diet, she had lost 10kg in just a few months.

“The way she got results wasn’t by starving herself; it was implemented through a structured programme,” Jono previously told Daily Mail Australia.

The Australia’s Next Top Model star faced backlash after revealing the results of her fitness challenge but chose to ignore her critics.

Simone and Jono met a few years ago when she was a client of the trainer.

They initially kept their romance under wraps before going public in May last year when they were spotted kissing at Mimi’s restaurant in Coogee.

Jono was previously married to Acero gym owner Amy Castano.
