Bindi Irwin Turns 15: Crocodile Hunter's Daughter's Style Evolution (PHOTOS)

Remember the little girl who made a heartbreaking eulogy for her dad, the late Steve Irwin, back in 2006?

Well the Crocodile Hunter's daughter is all grown up!

Bindi Irwin celebrated her 15th birthday on Wednesday at Queensland's Australia Zoo (where she lives with mom Terri and younger brother Robert) hanging out with the Animal Kingdom and taking a bite out of her zoo-shaped cake.

The cute teen tweeted her excitement over the day's celebrations and thanked her fans and loved ones for making the day special.

"What a beautiful 15th birthday I had. Thank you to everyone for the kind birthday wishes and support! I couldn't do it without you," Bindi tweeted.

Wearing some noticeable eye makeup, the animal-lover was clearly starting to experiment with her looks, as most teen girls do.

But Bindi isn't just any average teenager; the "Return to Nim's Island" star had her own TV show and even posed on the "Man of Steel" red carpet with none other than fellow Aussie Russell Crowe in June.

Crowe even tweeted out a happy bday to his young friend to which the excited beauty responded with enthusiasm.

Irwin's age also reflects her style maturity; as soon as she leaves the zoo, the khakis come off and in their place are glittery a-line dresses, bright floral frocks and plenty of prints.
