However despite admitting that she feels her late father Steve would 'have loved' Chandler, Bindi insisted the couple are in no rush to wed.

'For us we are happy just being together and enjoying the adventure. Why rush that next part of our lives as well?' 

Bindi's father Steve, died tragically just over 10 years ago, when she was eight years old.

Bindi has spoken before of her grief at losing her father so suddenly, telling Sunday Style in 2015: 'You never actually move on from it.'

'As a little kid, I remember people coming up to me and saying, "I'm so sorry [for your loss], sweetheart, but time heals all wounds",' she told the publication. 

'There really isn't a greater lie. It's just not true. It's like losing a part of your heart,' Bindi added.
