Looks like an oval or diamond to me.

Judging off Kims red carpet looks without lighting or editing; Her face is actually Oblong/Oval - oblong because it’s clear her face is usually longer then it is wide but oval because sometimes her face does look shorter and depending when she gets a bit of cheek filler making her cheeks the widest point which is why people often confuse it for diamond (the more cheekbone filler you get the smaller the jaw will look). She’s definitely oblong though because when her hair is pin straight her jaw and lower half is pretty noticeable and/or exaggerated. Her cheeks, forehead and jaw are all roughly even. That’s my take & why :) she’s a perfect example of an Oblong face when it’s balanced and how oblong faces can still very much be beautiful when balanced with the right makeup, features and proportions other then classic examples like Sarah Jessica Parker which is why people will often overlook oblong faces being an option for ultra beautiful women.
