The moment Bindi Irwin and Chandler Powell learned they were going to be parents is definitely one for the (baby) books. On Tuesday, the _Crikey! It's the Irwins_ star posted a photo to

Instagram of herself and her husband with their dog Piggy, sharing that she was "reflecting on when we found out that we are going to be parents" and adding, "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," recalled

Bindi, 22, in the accompanying caption. "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

going to share such wonderful, life-changing news with the people that we love," she said. "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," continued the _Dancing with the Stars_ season 21 champion. "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." Powell chimed in on the comments section, writing alongside a red heart emoji, "And we already love our little Wildlife Warrior with all of our

Bindi's mom Terri Irwin tweeted, "This is the best day ever! I am over the moon to announce that @BindiIrwin and @chandlerpowell9 are going to have a baby! Words cannot express

the love that is filling my heart." "While I wish that Steve was here to share this beautiful moment, I know that he would be so proud," added Terri, 56, who is also mom to

16-year-old son Robert with the late Steve Irwin. Steve (perhaps better known as the _Crocodile Hunter_) was killed during a diving expedition off the coast of Australia in September 2006.

He was 44. On her wedding day, Bindi was sure to honor her late father in her ceremony. "Where we got married was such a special place to Dad," she previously told PEOPLE of the

garden at the Australia Zoo. "It's a beautiful little area where he had filmed for many years. It felt really wonderful and just meant to be."
