The daughter of the late Crocodile Hunter, Bindi Irwin, posted a very sweet picture to Instagram of her and her little brother Bob, who is just 11, captioned: "This boy is my world."

The 16-year-old has been pretty open about losing her father in 2006 to a tragic stingray accident and this new picture with her brother shows off his stunning resemblance to the late icon.

This isn't the first time Bindi has posted about her beloved brother. On his birthday in November, she wrote, "He's one of my best friends and always manages to make me smile. He is more and more like Dad every day. I love him more than words and I'm so proud of the amazing human he is becoming."
