Kourtney Kardashian Once Again Defends Son Reign’s Long Hair

Kourtney Kardashian goes into mama bear mode against a social media user who criticized her 5-year-old son Reign's hair.

Monday on Instagram, the “Keeping Up with the Kardashians” star posted a carousel of images from Easter Sunday, featuring her children with ex Scott Disick — including son Mason, 10, and daughter Penelope, 7 — as well as the gifts she received from mom Kris Jenner.

“A Quarantined Easter story. (presents/baskets courtesy of @krisjenner),” the mother of three wrote in the caption.

Unfortunately, one critic took issue with Reign's long hair and wrote in the comments section, “Bruh cut your son hair...smh..”

That's when Kourtney clapped back by responding, “Most gorgeous hair on earth anyone who says otherwise ABCDEFG”

“ABCDEFG” is in reference to a 2015 episode of “KUWTK” where Kourtney, who was hired and then fired by Scott to be an interior designer for a project, abruptly ends their conversation by reciting the alphabet.

“ABCDEFG. I have to go,” Kourtney said in the now-viral clip.

“What the heck does ABCDEFG mean? Is that even a real phrase?” Scott asked.

“It's just a phrase I like to use that means the conversation is over. You've never heard that phrase?” she explained. “G [means] goodbye.”

Of course, this isn't the first time the Poosh creator has had to defend Reign's long locks against a troll.

After Kourtney posted pictures last October from a family vacation to Santa Ynez, California, a hater wrote to her that she “really [needs] to cut [Reign's] hair.”

In response, she wrote back, “She really needs to not worry about kids that aren't her own. He is a happy boy.”
