It's hard to believe Bindi Irwin is now 20!
It seems like only yesterday that she was a little rug rat scampering about with her father, Steve Irwin.
But the tot in khaki has grown up before our very eyes.
Bindi revealed in an interview with People magazine that she still grieves for The Crocodile Hunter, who died suddenly in 2006 after a stingray accident when she was only eight years old.
"That kind of sadness never goes away. It's like losing a piece of your heart that you never get back."
Bindi said that after her father died, "So many adults came up to me and said, 'Honey, time heals all wounds'…That is the biggest lie you will ever hear. It doesn't."
In spite of her immense loss, Bindi continues to carry on his good work as a young conservationist and wildlife champion.
"You can take the path that leads you down the aisle of sadness, or you can say, 'I'm never going to let this person's memory die. I'm going to make sure everything they worked for continues."
The animal activist is adamant about making her loved-ones proud.
"Mum and Dad are truly my heroes. And I have to say, so is my little brother Robert. He's 11 and he's just the most amazing boy. He's so much like Dad sometimes it's a bit scary. Dad is and always will be my living, breathing superhero."
We think Bindi is turning into quite the hero herself and Steve would be so incredibly proud of his eldest child.
