"You’re going to be the most incredible parents. We love you Baby Wildlife Warrior," Australia Zoo commented, while Powell left a heart emoji in the comments section.
"You both will be the most amazing parents! I can’t wait to watch your adventures with your little girl," one fan gushed. "This is so very heart warming," another wrote. "I’m not crying you are," a third fan joked.
Powell shared that Bindi has had to start borrowing his shirts to wear to work as "hers isn't buttoning over her gorgeous bump."
Bindi and Powell tied the knot in a surprise ceremony at the Australia Zoo in March 2020. They later announced that they had a bun in the oven.
"Baby Wildlife Warrior due 2021. Chandler and I are proud to announce that we're expecting!" Bindi wrote at the time.
"It's an honor to share this special moment in our lives with you. Though I'm still in my first trimester, we really want you to be part of our journey from the beginning of this new life chapter," she gushed. "We couldn't wait to share the news as this beautiful little being has become the most important part of our lives. Your support means the world to us."
Bindi’s dad, a.k.a. "The Crocodile Hunter," passed away in 2006, but Bindi has always made an effort to honor him, as the Irwin family continues to work with animals.
"Where we got married was such a special place to dad," Bindi said after she and Powell tied the knot. "It's a beautiful little area where he had filmed for many years. It felt really wonderful and just meant to be."
"We had dad's picture with his dog Sui blown up on an easel. So mom and Robert were standing right next to dad as we exchanged vows. We had a candle-lighting ceremony for him, and it really felt like he was there with us. It was a lovely moment of peace and happiness."
