Terri Irwin has shared childhood pics of Steve and son Rob and they look like TWINS!

It's been more than ten years since Steve Irwin passed away but now his son Robert has just made his solo television debut!

Robert, 13, delighted the New York City audience on Jimmy Fallon's The Tonight Show as he introduced the nervous presenter to Beetlejuice the African dwarf crocodile, Micky the screaming armadillo, Lady the red-tailed boa constrictor and Valentino the baby sloth.

Rob 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!"

Seriously watch this, he is SO much like Steve it's scary:

Following the show, Rob's Mum Terri shared this adorable side-by-side pic of Steve Irwin and Rob as child and we are seeing double!!
