Renowned Australian conservationist Robert Irwin was seen with his arms around Rorie Buckley, the niece of Heath Ledger, as they enjoyed a meal and watched the sunset at a beach in Queensland.
The couple were reportedly very private about their relationship.
However, it was clear that they were in love as they both smiled and held hands.
Buckley, who is the daughter of Kate, was also spotted with Irwin’s mother, Terri, at the Australia Zoo on his birthday last week.
