Kristin Cavallari is used to being judged by complete strangers, but she’s not holding back when Instagram commenters questioned her kids’ weight.

Last week, the former Laguna Beach star shared a vacation photo of her sons  Camden Jack, 3½, and Jaxon Wyatt, 2, enjoying the Fourth of July holiday.

“Even though we’re not in the States, we’re still celebrating,” she captioned the photo of her “guys” playing with snorkeling gear in matching striped swim trunks. “Hope everyone has a fun and safe 4th!”

The innocent photo started drawing criticism from social media users saying her children looked too skinny.

“I understand you live a very strict dietary lifestyle but these children are very obviously nutritionally deficient,” one Instagram user wrote.

“Seeing pictures of your boys and how they look is a bit shocking to see! I know you cook healthy but to see the bones just doesn’t seem normal, sorry!” read another comment.

Cavallari, 29, responded by blocking the offenders and penning a sarcastic response to their “concerns.”

“Yep, I starve my children,” she wrote. “Just blocked the most people I’ve ever blocked in my entire life. Happy 4th hahaha.”

The reality star and her husband Jay Cutler, 33, have been open about her family’s healthy diet. In her book Balancing in Heelsshe explains how she’s “become a psycho about reading every single ingredient label and researching the ingredients I don’t recognize.”

She says eating mostly organic and only wild-caught fish or grass-fed beef has also helped Cutler manage his type 1 diabetes — and keep her kids healthy.

“His insulin use is down, and he’s off his blood pressure medication. And he looks the best he ever has: His weight is ideal and his skin is clear. I really believe that my family’s infrequency of getting sick is due to our diet.”
