Kristin Cavallari is less than thrilled about Instagram users questioning her parenting skills.
The skinny-shaming started when the former "Hills" star posted a photo of her husband and two sons playing on the beach last week.
Shortly after posting the photo, people began commenting on how thin her children looked.
One commenter wrote, "You can see the back of their rib cage. Wtf you dumb b**ch! They are growing boys!!! They need to eat non-stop."
Several others defended Cavallari.
Another commenter wrote, "Oh my god, can't believe what I'm reading , your kids are probably like mine out playing all day and not in front of the TV or at their iPads, your an active parent that actually get outs and does stuff with them, instead of buying new DVDs every week."
Cavallari, however, wasn't having it.
She quickly fired back saying, "Yep, I starve my children. Just blocked the most people I've ever blocked in my entire life. Happy 4th hahaha."
