Bindi Irwin at 14: Crocodile Hunter's daughter growing up fast

Bindi Irwin is back in the spotlight promoting her new film, "Return to Nim's Island," looking much older than the pig-tailed young girl you might remember.

The 14-year-old daughter of "Crocodile Hunter" Steve Irwin, who died in 2006 after a stingray barb pierced his chest, is following in her father's footsteps as an animal activist and conservationist.

But she's also added acting to her already impressive resume, starring in the sequel to Abigail Breslin's 2008 film, "Nim's Island," which premieres on The Hallmark Channel on March 15.
