"Bruh cut your son hair…smh," one follower wrote in the comments section. Kourtney replied, "Most gorgeous hair on Earth. Anyone who says otherwise ABCDEFG." Zing!
ABCDEFG is a phrase Kourtney has used in the past, explaining she uses it when she wants to end a conversation.
'It's just a phrase I like use...that means the conversation is over,’ she said in a KUWTK episode, revealing that the ‘G’ stands for ‘goodbye’.
Several fans were quick to defend Kourtney's choice to keep Reign’s hair long, with one writing: 'He's aloud to have long hair if he wants and stop telling people what to do with there own kids x his hair is lovely [sic].'
Earlier this week, Kourtney – who shares children Mason, Penelope and Reign with ex-partner Scott Disick – appeared to hint that she was ready to have another child.
The Poosh founder shared a revealing photo with fans, which prompted speculation she was pregnant.
While she shut down the conversation pretty quickly, she not so subtly suggested she'd love to give her kids another sibling, however, didn't say when.
"Put the blessing out there though 🙏🏻," she replied to a follower who asked, "are you pregnant?" before another added, "Nope, wish she was."
