It comes after Madeline gave a glimpse at her notoriously private romance with Merivale boss Justin..

She posted a sweet tribute to him on Instagram in February, to mark Valentine’s Day.

A bikini-clad Madeline was seen kissing Justin in one photo, while in another the couple is pictured together on his seaplane. 

‘Valentine’s Day every day with you,’ she captioned one photo. 

Agents have reportedly been warning Madeline she could be missing important opportunities in the modelling industry because she is prioritising her relationship over her career. 

‘It’s not like Madeline is going out with a Hemsworth,’ one industry source told The Daily Telegraph.

Pair: Madeline and Justin have been dating for some time, and she also spent lockdown at his Vaucluse mansion in 2020

‘I don’t think this relationship with Justin will have much of an impact on her career. If anything, she will be more known as a bit of a celebrity model as opposed to a fashion model.’ 

Another source close to the couple said: ‘It’s all well and good now, but there might come a time when the relationship runs its course and she will need her modelling career, so she can support herself financially.’
