'Proud mumma. Soldier on NB. It's what we do...' she wrote in an Instagram Story on Sunday.
Speaking to Stellar on Sunday, Nadia, 34, admitted 'every day is tough' as she adjusts to life as a single mother, saying: 'This is never what I thought would happen.'
The 34-year-old admitted it was particularly hard to see hateful comments written about her online.
'I was at the hardest point in my life and then to have articles written that weren't true, and to have hundreds of hate [comments] on Instagram and the continual pounding... it was difficult,'
However, the Melbourne-based fashionista says she is focusing on all her attention on the former couple’s two sons, Aston, four and Henley, one.
'I want my boys to be aware of their feelings. And if they are feeling a certain way, they can show that feeling. They are allowed to cry and allowed to come to me and say what's happening'.'
