Robert Irwin Looks So Different With a Mustache in New Transformation

Robert Irwin tried out a new look in the wild.

The wildlife conservationist debuted a brand new mustache in order to prank his mom Terri Irwin, and the results were priceless.

“It has been a minute since I shaved,” Robert said in a Jan. 3 TikTok while showing off his grown out facial hair. “I’ve had like a week off filming, but I’m about to go back on set, so I’m going to take this opportunity to play a little prank on the crew.”

The 22-year-old could barely contain his laughter while trimming his beard into what he called a “perfect” mustache.

He even had some fun impersonating different pop culture references, including a pilot from Tom Cruise’s hit movie Top Gun and Nick Offerman’s mustachioed Parks & Recreation character Ron Swanson.

When Robert—son to Terri and her late husband Steve Irwin—arrived on set, he was greeted with screams of surprise (read: disgust) and some playful banter from his mom, who said, “As your mother, I’m incredibly proud.”
