Terri Irwin shares amazing side-by-side photo of Steve and son

It's been more than ten years since Steve Irwin passed away but his son Robert is certainly following in his famous father's footsteps. 

Just a few days ago, Robert, 13, delighted the New York City audience on Jimmy Fallon's The Tonight Show.

Bob spoke so passionately about his life at Australia Zoo that Jimmy said: "It's so cool to see you like this - you're your dad!"

Following the show, Terri shared this adorable side-by-side pic of Steve Irwin and Rob as a child and we are amazed at how similar the two look:

After seeing Bob on screen it's quite clear that the 13-year-old is doing incredible justice to his Dad's legacy.
