And it seems that amid the criticism around the photo, there are a lot of people on Kim's side.
Many people are suggesting that nobody would care half as much if it had been a man who'd posted the selfie.
And others are saying that when male celebrities get naked – whether in selfies or in movies – no one bats an eyelid.
And that there's a disconnect in the way we view and react to male and female celebrities.
Another criticism is that Kim shouldn't be posting nude selfies because she's a mother.
But plenty of people think her role as a mother has nothing to do with her decision to share these images.
Mainly on the basis that she can do what she wants with her body.
Kim's also come up against the accusation that she's only famous because she posts naked selfies.
Others don't think that's true.
And, after Kim completed her rant against other celebrities, she shared another nude photo alongside the caption: "#liberated"
And the fact she's confident with her body and feels liberated by sharing these images is another reason people are defending her posting them.
It's also something Kim herself has spoken about in the past, explaining that she shares these kinds of selfies as an expression of confidence.
Speaking to Rolling Stone last year, Kim revealed: "I do shoots that are nude, and I don't want to say every girl, but all my girlfriends send me these sexy selfies of themselves, just being like, 'Oh, my God, I've been working out for two weeks — look at how good of shape I'm in.' Girls send them to each other. I don't want to say it's normal, but it's just what I've been used to. . . And I think it's part of the whole selfie phenomenon."
