The wildlife activist cutie sent fans into a tailspin when he posted an Instagram photo of him posing with young artist Tess Poyner.
"A big happy birthday to @tess_poyner. It was so fun to attend the Australian Geographic Nature Photographer of the Year Awards ceremony with you," the 13- year-old captioned the pic.
“It is wonderful that you were the runner up in our category with your amazing kangaroo photo. Hope you had the best birthday ever!”
With both Robert and his sister Bindi following Tess, followers were quick to pick up on the possible new pairing.
"Awww, I see a crush," teased one, while another said: "You’d be cute together."
