Once again, 15-year-old Bindi Irwin proves she's wise beyond her years!

The self-proclaimed "Wildlife Warrior" took to Instagram on July 20 to wish her mom Terri a happy 50th birthday, writing:

"Happy birthday to my everything. Mum, you are amazing. You have always been there for me and Robert, and have loved us no matter what. Everyday I think about how blessed I am to have you in my life. You are the most beautiful mother on Earth. I know that Dad is so proud of you and so are we. I love you. Forever."

It's been eight years since the tight-knit family was rocked to its core when patriarch Steve Irwin, aka "The Crocodile Hunter," was killed by a stingray barb in a freak accident.

Bindi and her 10-year-old brother Robert have since carried on their father's legacy and passion for wildlife. She is set to celebrate her 16th birthday this Thursday (July 24) at the Australia Zoo.

The adorable teen's eloquent tribute to her mother should come as no surprise to those who follow the charismatic blonde's many activities. Earlier this month, she posted a make-up free selfie, encouraging girls to "let your inner light shine."

The activist has also commented that she enjoys dressing her age, refusing to wear clothing that shows a lot of flesh.
