The reality TV star, 34, posted the picture on Saturday (28 February) telling her fans she was feeling a little bit grumpy!
While we're more used to seeing Kim with perfectly contoured cheeks and expertly applied make-up, she can be seen totally bare-faced in the snap.
And she STILL looks stunning!
Alongside the snap - where Kim is poking her tongue out - the mum-of-one also proves she is only human when she admits she's having a bad day.
She says: "UGH just got off a plane, so tired, have a shoot tonight, need a tan, not in the mood!"

Of course, Kim's adoring fans were quick to tell her what they thought of her no make-up selfie.
And the words "goddess" and "amazing" come up quite a bit!
One fan described Kim as "naturally beautiful as always", while another added: "You don't need a tan. You don't need makeup. You are blessed."
Just a few days ago, Kim revealed her top beauty buys, including affordable face wipes.
Kim has just returned to the US after a whirlwind visit to the UK to attend the BRIT Awards, where she presented an award and Kanye performed.
Also this week, Kanye made no secret of the fact that he and wife Kim are "trying really hard" to give daughter North West a baby brother or sister...
