Chandler Powell's birthday tribute to Bindi Irwin leaves fans in tears: 'Sobbing'

Chandler Powell left fans in tears after sharing a sweet birthday tribute to wife Bindi Irwin on Monday, with the 26-year-old enlisting the help of the pair's daughter Grace Warrior and people around Australia Zoo, including Robert and Terri Irwin.

Chandler kicks off the video showing him and Grace with several kangaroos, as he begins singing happy birthday, she sweetly sings, "Happy birthday dear kangaroo!"

"Kangaroo? We're singing it for momma, not a kangaroo!" Chandler says with a laugh, then, looking at the camera, adds, "Happy birthday mamma, we love you!"

The four-minute video then sees Australia Zoo employees share the one word they'd use to describe Bindi, with many saying 'beautiful', 'inspiring' and 'passionate'.

Robert then appears on screen, sharing his own tribute, saying, "Bindi, happy birthday! We love you so much, I love you so much. Thank you for being such an awesome sister. The most cool, incredible, hardworking, passionate, determined individual.

"You inspire me every day and you're always there to give advice on the little things to the huge, huge things. And I think we can all take a page from your book, especially these last couple of years that have been so difficult. In the face of such massive challenges, these huge health struggles, you have just sailed through with such grace and amazing steadfast conviction."

He continued, "You're an incredible mum to Grace, and I just want to say thank you for being there for me every day for the last 19 years that I've been alive and I love you very, very much."

Bindi and Robert's mum Terri also shares a sweet tribute in the video, saying Bindi is making her dad Steve Irwin 'so proud'.

"It's a wonderful year," Terri said of turning 25. "And I'm so proud of everything you've achieved with your beautiful family, being CEO of Australia Zoo and making your dad so proud of everything that you do."

Chandler captioned the video, "Happy birthday to the most strong, kind, & beautiful person that I know. Your kind heart is my favorite thing about you. I have new admiration for the strength you have mustered to find your new chapter of health. It’s been incredible to watch you blossom as you continue to improve each day. I love you. Grace loves you. You are our world."

Bindi commented, "Oh my goodness. This is the most thoughtful birthday video. I love you so much."

Fans were emotional after watching the video, with one user writing, "Happy birthday Bindi!! I'm just over here crying my eyes out over this sweet video tribute to you! You so deserve every kind word that was said!"

"Anyone else sobbing?!? Happy birthday, Bindi," another added.

"Ahh I'm literally crying, happy birthday, beautiful," a third wrote.

"Let’s all pass the tissue box, Happy Birthday, Bindi!" someone else said.

"I did not know you were CEO of Australia Zoo Bindi!" another said. "And that was just a minor point amongst all the amazing things said about you! Happy birthday."

Others also questioned if Grace's accent was Australian or American, with it sounding like a bit of a mix given she's around two Americans with her dad and grandmother.
