Asked if that means she is planning another child, she replied: "Not yet. Not until after we get married. My partner is very traditional.
"We can't... I mean, we're just... waiting."
The Australian beauty - whose due date isn't known - previously spoke of how she did her best to stay healthy during her first pregnancy.
She said: "I practiced yoga throughout my whole pregnancy and I eat really healthily and I just continued that, really. I have been working out. I've been doing resistance training and some good squats, sit-ups and all that stuff."
And she previously described being a parent as a "huge honour".
Asked about the biggest challenge of parenting, she said: "I think it's the responsibility of raising a child to be the best version of themselves. Thinking back, the sleep deprivation for the first year was pretty challenging too! But the sleepless nights were well worth it.
"Being a mother is just a huge honour. My favourite part of the day is picking Flynn up from school. Seeing his little face light up when he sees me! It is joy and love in the purest form. It's just magical seeing him grow and develop his own personality."
