The public first met Bindi Irwin years ago when she was featured on her late father's TV show, "The Crocodile Hunter." Now, nearly seven years after his death, it's clear that his little girl is all grown up.

Irwin, who at one point had her own show, "Bindi the Jungle Girl," is following in her dad's footsteps and celebrated her 15th birthday Wednesday at the Australia Zoo.

"So excited to be 15 today," she tweeted. "I'm feeling blessed to be spending my birthday with my wonderful friends and family @AustraliaZoo"

During the celebration, which included the teen's mom, Terri, and 9-year-old brother, Bob, Bindi Irwin wore an "Australia Zoo" khaki shirt and shorts, did a demonstration with a crocodile, cuddled with a koala, and cut into a wildlife-themed cake.

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