Merry Christmas 🎄

A post shared by Kim Kardashian West (@kimkardashian) on


Kim Kardashian is under fire for letting her 5-year-old daughter North wear red lipstick to the family Christmas party ... and you know the online trolls aren't gonna let this one go!

One commenter wrote, on a family pic Kim Instagrammed: "Don’t start this little girl on red lipstick! That’s for grownups. Come on." Another one wrote: “It’s wrong for kids to wear makeup. It’s not normal. It’s not natural. Period."

Kim hasn't responded -- and let's get real, she's made a significant part of her fortune from her makeup line so it'd be like telling a the CEO of Keebler not to feed his child cookies, I mean ...

That said, between the straight hair, the red lipstick and the practiced Insta-pose, it looks like Nori's a little ahead of the game, being only 5. What do YOU think?
