In a recent Instagram post, Irwin updated her followers on the status of her pregnancy.

"Baby Wildlife Warrior is about the size of a hummingbird now! We can't wait to teach our little one about the importance of protecting our planet and the beauty of the wildlife and wild places we love so much. Thank you for your kindness and support on this magical journey," she wrote.

She added that the other animals at Australia Zoo "are excited to meet our human joey."

In a separate update, Powell revealed that he is excited for what the future holds.

"Our little human joey with some of our Australia Zoo joeys. Can't wait for our baby to meet everyone in person. Being a dad is already the highlight of my life," he wrote on Instagram.

Just because Irwin is pregnant, it doesn't mean that the work at the zoo stops. 

"She's made it her mission to keep her father Steve legacy alive. But Bindi's fried at the end of the day, she barely eats or sleeps, and then she's up before dawn to begin the vicious cycle again," a source revealed.
