The 14-year-old was photographed in Australia this week while promoting her new movie, Return to Nim's Island. In the film, Irwin plays a teen castaway previously portrayed by Abigail Breslin in 2008's Nim's Island.
Irwin inherited a love of nature from her father, who was killed in 2006 after being stung in the chest by a stingray. She regularly participates in conservation efforts and wildlife exploration with her mother, Terri, and younger brother, Bob.
Are you surprised to see Bindi all grown up?
