Don’t come between a mother and her son’s long locks!

Kourtney Kardashian defended her 4-year-old son Reign when she clapped back at criticism of his long hair.

The mogul posted a series of photos on Instagram of Reign and his sister, Penelope. But a commenter later wrote, “She really needs to cut his hair.”

That’s when the Keeping Up With the Kardashians star replied, “She really needs to not worry about kids that aren’t her own. He’s a happy boy.”

We agree! Enough of the mom-shaming, right?

We WISH our hair had that glow.
