Bindi Irwin says ''time stood still'' when she learned she is pregnant.

The 'Crikey! It's the Irwins' star is currently expecting her first child with her husband Chandler Powell, and has taken to Instagram to reflect on the moment she and her spouse found out they are going to become parents.

Alongside a picture of herself with Chandler and their dog, Piggy, Bindi wrote: ''Reflecting on when we found out that we are going to be parents. Discovering that I was going to become a mother will forever be a moment where time stood still. I took a test and ran into the kitchen where Chandler was making us tea. He didn't hear me come in so I speechlessly watched him pouring the water into my most loved hedgehog mug. This news would change the course of our future in the best way. I started crying tears of pure joy and told my sweetheart husband that my test was positive. (sic)''

The 22-year-old conservationist - who is the daughter of the late Crocodile Hunter, Steve Irwin - went on to say her unborn baby is already ''the most important part'' of her life, and insisted she can't wait to welcome her ''baby Wildlife Warrior'' into the world.

She added: ''We were beaming while our adorable puppy Piggy sat on our feet wondering what was going on. It reminded me of just how perceptive animals are. We sat together with tea talking about the future and how we were going to share such wonderful, life changing news with the people that we love. In that short span of time the gorgeous baby I'm carrying became the most important part of our lives.

''It is such a blessing knowing that this tiny person has chosen us as parents. Our baby Wildlife Warrior is going to be so very loved by our families and entire Australia Zoo team. I can't wait to find out what this amazing new soul loves in life, and experience the world all over again through their eyes. (sic)''

Soon after she posted her glowing tribute, Chandler responded in the comments: ''And we already love our little Wildlife Warrior with all of our hearts (sic)''
