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

Simone Holtznagel is already missing the sun and sand of Bali.

The model and influencer, 29, posted a gallery of throwback snaps on Instagram from her trip to the Indonesian party island last month with boyfriend Jono Castano.

She displayed her recent 10kg weight loss in a series of patterned bikinis as she and Jono lounged around their luxury accommodation at The Mulia Resort and Villas.

‘Bali MEMS we saw everything,’ she wrote in the caption.

All the photos had the same amusing theme: Simone would be smiling and taking a selfie while her beau would be asleep next to her.

Their overseas trip comes after Simone debuted her body transformation in August.

She had lost 10kg in just a few months with the help of her boyfriend, who oversaw her regular workout sessions and helped plan a well-balanced diet.

‘The way she got results wasn’t through starving herself; it was done through a structured program,’ Jono previously told Daily Mail Australia.

The Australia’s Next Top Model star copped backlash when after she unveiled the results of her fitness challenge, but decided to ignore her critics. 

Simone and Jono met several years ago when she was one of the trainer’s clients.

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

Jono was previously married to fellow Acero gym owner Amy Castano.
