Bindi Irwin had the most classic big sister reaction to brother Robert Irwin’s viral thirst traps.

“I will say there are some things as his sister that I can’t unsee,” the conservationist, 26, said while laughing during the Thursday, June 5, episode of Kylie Kelce’s “Not Gonna Lie” podcast. “When he did the Dancing [With the Stars] announcement, he was shirtless, and he recently did his Bonds commercial where he was in his underwear.”

She continued: “It is rough, I really want to be supportive. I really am so proud of him. He’s taking the message of conservation to new heights.”

Kelce, 33, added that when Robert, 21, was going viral on social media, she noticed there were varying reactions to him from different age demographics.
