In her snap, Kourtney appeared in a white lingerie outfit, wearing high heels and sporting what looks like the famous Victoria Secret angel wings.
While many fans admired Kourtney's gorgeous outfit, others criticized the Instagram diva's room for being rather dirty and unkempt.
One user picked on Kourtney for narcissism: "Apparently self grooming and room grooming are in 2 different categories!"
Another user noted: "That room is dirty as hell though!"
"Clean that damn room before taking pics WTF," wrote another one.
However, there were users who stood up for Kourtney, despite the way her room looked: "HOLY **** this girl is SEXY. who the HELL is looking at the room?…"
Earlier this week, the curvy squad from the famous reality TV clan appeared on Halloween, wearing almost nothing but feather wings and sexy lingerie.
