However, the brunette beauty's supporters, led by her momager Kris Jenner and devoted husband Kanye West, have come back fighting over the pictures taken by legendary photographer Jean-Paul Goude. Kris tweeted: "Looks like someone's going to break the internet".
Meanwhile, her son-in-law posted one of the pictures with the cryptic hashtag #ALLDAY – probably meaning he could look at it all day long.
It's reminiscent to Kanye's reaction when his wife published a revealing swimsuit selfie, showing the result of her post-baby workout. On that occasion the rap genius told fans: "HEADING HOME NOW".
Kim's BFF Jonathan Cheban wrote a long blog post addressing comments by Glee star Naya Rivera, who had written on instagram: "I normally don't... but you are someone's mother." .
He accused the actress of a "year-long tour of impersonating Kim". He added: "Yes, Kim is a mother, BUT WHO CARES."
His Twitter post to the same effect was re-tweeted by Khloe Kardashian.
Meanwhile, Piers Morgan, who says he knows Kim socially, praised the reality star for her business acumen. He also pointed out that "she doesn't take drugs, get drunk, fall out of clubs, cheat on her man.....
"She works ridiculously hard, is good to her fans, and is by all accounts a good, loving daughter, sister, wife and now mom herself.
On Tuesday, Kim posted the racy images, which are in Paper magazine, to her 22 million followers instructing them to #breaktheinternet – a hashtag that was soon trending.
The pictures evoke the aftermath of a wild party, showing Kim taking off her dress with a bottle of champagne and other party debris at her feet.
In the arty cover photo, the star appears fully dressed, having just opened the bottle of bubbly. The cork appears to fly out and the foam lands behind her in a glass balanced on her famous derriere.
Kim joked: "And they say I didn't have a talent...try balancing a champagne glass on your ass LOL #BreakTheInternet #PaperMagazine"
For the cover shot, French artist Jean-Paul, a longtime collaborator of Grace Jones, recreated an image that appeared in his 1982 book Jungle Fever.
