Steve Irwin’s Teenage Son Robert Looks Just Like Him — See the Side-by-Side Photo!

Last night, Steve Irwin's son Robert dropped by "The Tonight Show Starring Jimmy Fallon.”

During his second appearance on the show, Fallon brought attention to the 13-year-old's striking resemblance to his late dad. Along with showing side-by-side photos of Robert and Steve, Fallon told Robert that he is “a spitting image.”

In response to the photos, Robert said, "It's a bit wild. When my mom first showed this to me, I thought it was me. I can't tell them apart. I said, 'It's me. What's the big deal?' Until you look at dad's shirt, you don't even realize that it's two different people.”

Robert made his debut on the show in February, grabbing the attention of 54 million people on Facebook. He shared, "One of the friends who was traveling with us at the time kept going, 'Look! It's up to 10 million! Look! It's at 20 million!' It was an incredible experience for me, so thank you so much for having me back. We have so much fun.”

Along with getting used to the spotlight, Robert also gave Fallon a chance to play with baby bears, a binturong, and two legless lizards. Watch!
