Terri Irwin and the late Steve Irwin's 12-year-old son stepped out at Australia Zoo to celebrate Steve Irwin Day on Tuesday, Nov. 15 — and we can't get over how grown up Robert looks in the new pics!

Steve — who sadly passed away in September 2006 at age 44 after being fatally stabbed by a stingray while snorkeling in Australia's Great Barrier Reef — and his wife, Terri, 52, welcomed Robert in December 2003.
The couple — who married in 1992 — are also parents to an 18-year-old daughter, Bindi Irwin.
