Little brothers—can't live with them, can't live without them.
Bindi Irwin and her sibling are no exception to the rule. While the Dancing With the Stars winner and her boyfriend, Chandler Powell, were walking along the beach to find the perfect spot for a photo op, the duo suddenly became a trio.
"When you're trying to get a gorgeous beach video & then BAM! @robertirwinphotography arrives," the star captioned a video on her Instagram account.
As Powell's camera rolled, Irwin's brother Robert joined in on the fun by running back and forth in front of the lens with his surfboard in hand. While the goofy move may have frustrated his sister just a touch, the moment was precious all the same.
While Robert may crash his sister's dates, at the end of the day, their bond is unbreakable. "Thank you for making me laugh every day," Bindi wrote to Robert on his 13th birthday. "I'll always be here for you."
Though the two faced the loss of their famous father, Steve Irwin, when they were just children, Bindi is reminded of her dad every time she's with her brother.
"Robert is so much like dad it's crazy," she previously told Daily Mail Australia. "He is the spitting image. Just his mannerisms, everything about Robert is like dad."
"No matter what happens in life we've got each other's backs," she added. "Robert often says I'm kind of like a mother."
