It's been less than 24 hours since Kim Kardashian attempted to "break the Internet" with her butt-baring Paper Magazine cover, and already some stars are slamming the overtly sexy shot.

Kardashian's lookalike, Naya Rivera, wasn't too thrilled about the photo and let the Internet know it. In response to the Instagram image, the 27-year-old actress commented directly to the post on Tuesday night, writing: "I normally don't. But... you're someone's mother..."

The "Glee" gal wasn't the only celebrity to call out the "Keeping Up with the Kardashians" star being a mother to North West and also posing nude. Pop star Lorde re-tweeted Kim's NSFW photo with a message that simply read: "mom."

Comedians are having a good time with the cover.

Chelsea Handler posted her own nude shot on Instagram, writing: "Can you believe more than 2 ass can fit on the same screen? Guess which one's real. Your move, Instagram."

"Billy On the Street" star Billy Eichner also got a few laughs with his Kim K. tweets. Our favorite reads: "If ur already as sick of looking at that pic of Kim Kardashian as I am here's a pic of Bob Hope to cleanse the palate."

Meanwhile, Kim has been getting support from her family and husband after Instagramming the bootylicious images. Kanye West re-tweeted the butt-baring cover with the hashtag: "#ALLDAY."

Momager Kris Jenner also tweeted her excitement for the big Paper Magazine reveal, writing: "Looks like someone's gonna #BreakTheInternet @kimkardashian!!!"

Jennifer Lopez might also disagree with Rivera and Lorde. After the release of her "Booty" music video, ET asked the 45-year-old entertainer how she handled the criticisms that her image in the video was too sexual. "I refuse to be put in a box in that way," she proclaimed. "Why, because I'm over 40? So I can't be sexy? Or, is it because I'm a mom? Moms aren't allowed to be sexy. Uh, how did I get my kids in the first place?"
