The 24-year-old Australian reality TV star took to social media to gush about her love and appreciation for her not-so-little brother. In the photo she posted to Instagram, Robert towered over his big sis–who was wearing a plaid flannel, black shirt, and jeans while he donned a sheer white polo shirt and jeans as he pretended to hit his head on the overhang that was outfitted with a “watch your head” sign. Along with the rather ironic photo, his big sister shared a very heartfelt message–that will likely bring tears to your eyes, so grab the tissues (and don’t say we didn’t warn you). “Happy Birthday to the taller Irwin sibling and greatest brother in the world. You light up our lives with your hilarious sense of humour and kind heart. I see so much of Dad in everything you do and I know he would be beyond proud of you. We all are,” she wrote, referencing the two’s father, Steve Irwin, who tragically passed away in 2006. Irwin’s caption continued: “Thank you for being such a good uncle to Grace and fantastic brother to me and Chandler. We love you and can’t wait to celebrate today!” “Love you B 🧡😊 thank you!” Robert commented back. And from the look of the rest of the comments section, a lot of Irwin fans have to deal with drastic height differences between themselves and their youngest siblings. “Those lovable younger brothers always growing past us awesome older sisters lol. Happy birthday Robert!!!! 🥳🥳,” one fan chuckled. Another questioned, “Why is it that the younger ones always get to be taller than us? 😂” And while it looks like the science of birth order and height is still out, Reddit users are determined that they will eventually reach a conclusive answer.
