The blonde beauty styled her hair up in a low bun and carried a neon pink water bottle.

She completed her sleek activewear look with a touch of designer items - her Prada sunnies and a YSL handbag.

Her pal Indi - who launched an OnlyFans account in August - opted for a similar all-black look in a unitard but white trainers as she carried a large water bottle.

At one point Madeline stepped out of the gym and appeared to pay to extend her parking at a metre before returning back to continue exercising. 

While it's not known exactly how long Justin and Madeline have been dating, she hinted their relationship has carried on longer than many people may think.

Speaking to The Sydney Morning Herald in October 2020, Madeline said they'd actually met two years before reports emerged of their relationship early last year.

'We have known each other for two years and met when I was modelling in Singapore,' she said at the time.

She noted her parents and sister Anna were yet to meet her beau at the time.

Only her other sister Simone - who was a finalist in the 2011 season of Australia's Next Top Model - had met him at that point, saying she 'really liked him'.
