Taking to Twitter, Terri, 53, made a comment about their relationship.
“After many years of @BindiIrwin kissing frogs, it finally paid off! #KissMeImIrish,” she captioned a collage which featured an adorable childhood photo of Bindi holding a frog and snap of her and Powell, 21.
This came shortly after US-born Chandler posted a heartfelt message to his girl.
“Moments like these walking by the river with my girl are what I live for. This photo encompasses what our every day is about, constant laughter and no clue of where life will take us that day. That is the best way to live Thank you Robert for capturing this special moment!” Powell wrote.
Fans were quick to react to the photo and even questioned if it were an announcement about the couple's relationship status.
"When's the wedding?" one wrote.
Meanwhile, Bindi replied to Chandler's post: "‘I love you’ doesn’t even come close to describing how much you mean to me❤️."
Neither of them has confirmed they're engaged, but here's hoping!
