Robert Irwin and Rorie Buckey were matching in all-black ensembles as they made their red carpet-debut as a couple.
The 19-year-old son of late Crocodile Hunter star Steve Irwin and the 18-year-old niece of late actor Heath Ledger stunned as they made an appearance at the premiere of Mission: Impossible - Dead Reckoning Part One in Sydney, Australia.
The wildlife photographer was all smiles as he sported a simple black suit, while his girlfriend coordinated with an asymmetrical black gown with a side cutout.
The young couple did not shy away from displaying affection in front of the cameras as in one of the poses, Irwin held Buckey around her waist as they smiled gracefully at photographers.
Fans have shared their awe-struck reactions to the lovely couple's first official public outing. One user wrote: "Robert Irwin and new girlfriend Rorie Buckley are just so adorable."
Another user quipped: "Nothing will ever embarrass me because my parents witnessed me on the floor laughing hysterically and crying bc Robert Irwin hard launched his girlfriend."
A third person still couldn't believe that Irwin is dating the late actor's niece and remarked: "ROBERT IRWIN IS DATING HEATH LEDGERS NEICE."
And a fourth user quipped: "Robert Irwin is dating Heath Ledger’s niece??? uGHHH i love Australian Royalty."
Buckey is the daughter of the late Dark Knight actor's sister Kate - who owns a design and media production company - and Nathan Buckey, a floor coverings store owner.
Daily Mail reported that she is studying for a Bachelor of Science in Physiotherapy at Curtin University and also has an identical twin sister named Scarlett.
She first sparked romance rumors with the son of the late conservationist - who tragically passed away in 2006 while filming Oceans Deadliest - after the pair were spotted on a date at a fine dining restaurant in Brisbane, Australia late last year.
They looked loved up as they sat side-by-side at the outdoor restaurant, with Irwin donning a navy button-up shirt while the college student sported a black backless top.
Irwin and Buckey have since been photographed out together a few more times, including at Perth Airport in April. They even have family support as Buckey's father told Daily Mail Australia that he "absolutely" approved of their relationship.
The red carpet debut comes after Irwin was attacked by the same species of snake that bit his dad.
In a video uploaded to Twitter, the conservationist could be seen holding a carpet python, which lunges and bites his face. Despite bleeding from a pretty nasty wound, he shrugs it off and even smiles at the camera as he jokes: "Luckily it didn't get my eyeball".
Captioning the video, Robert wrote: "Déjà vu. Dad and me getting bitten by the same species of snake (carpet python) decades apart. I found this python on the side of a road, but as you can see, sometimes snake rescues don’t quite go to plan."
