Talk about a sibling rivalry! Noah Brown took to social media to slam his little sister, Rain, and his words were pretty harsh. The Alaskan Bush People star, 25, called out the 15-year-old for having zero responsibilities… and we're actually cringing.

"When you are a child like little Raindrop, you do not have to think about what you are going to eat for dinner or worry about paying bills because your parents do everything for you and you cannot take care of yourself," he wrote on Facebook. "Young Raindrop spends her days cuddling bunnies and playing with her dolls not knowing about the stressful lives of the adults around her." Ouch.

The teen often shares videos of herself singing, dancing, and working out and even calls her fans "rainbows." Most recently, however, these "rainbows" accused her of having bad form while doing pull-ups.

"Nine months ago I couldn't even do a half of a pull up and now I can do 14 I'm so proud of myself and how far I have come never give up on your dreams and goals because If you start now who knows maybe nine months from now you could be halfway to your goal," she wrote. In response, someone commented, "You gotta stretch your arms so it counts as a pull-up." A second added, "That's half of a pull-up," and a third asked, "Aren't you supposed to come above your chin and go down further?"

Noah is getting married in just a couple of months — to a woman named Rhain, no less — and although things seem tense between the siblings, she's at least got the support of her other brother, Gabe. The reality star shared a snap of herself alongside her big bro and his girlfriend on Instagram and wrote in the caption, "Third wheelin like a pro." Here's to hoping the two can mend their relationship before his big day!
