The Australian stunner, 29, smiles defiantly as her naked baby feeds, and the photo has prompted Elle's editor-in-chief, Justine Cullen, to defend the decision to have a nursing mum on the cover.

She says, "This wasn't a contrived situation. Zion needed a feed, Nicole gave it to him, and when we saw how beautiful they looked we simply moved her onto the set. It was a completely natural moment that resulted in a powerful picture."

Reports suggest little Zion also relieved himself on the designer clothes his mum was wearing for the shoot.

Trunfino is thrilled with the cover shot, hoping the breastfeeding picture will empower other new mums.

In a post on Instagram, she writes: "There is nothing more powerful and beautiful than motherhood. The last thing I want to do is be controversial, so please take this for what it is... There is nothing worse than a mother that is judged for feeding her hungry child in public.

"I'm so proud of this cover and for what it stands for. I obviously don't look like this while I am breastfeeding but this stands for all women out there, whether you breastfeed or not, we gave birth, we are women, we are mothers. Thank you to ELLE for being so bold and making such an encouraging, positive and healthy statement."
