The Australian wildlife warrior covered her bump in her signature khaki work uniform, blue jeans and sneakers.

Robert couldn’t wipe the smile off his face as he posed with his mother, sister and his brother-in-law next to an extravagant cake.

The 17-year-old – who is the spitting image of his late father, Steve ‘The Crocodile Hunter’ Irwin – was also dressed in Australia Zoo’s signature khaki uniform.

Steve Irwin died in September 2006 at the age of 44 after being pierced in the chest by a stingray barb while filming a documentary in Batt Reef, Queensland.
