The photos stirred up a lot of controversy online, with some people decrying the pics, while others supporting Kim's choice to pose nude. Other people wondered why it was even a story in the first place.
However, ET's Rocsi Diaz spoke with Kim's sisters, Khloe Kardashian, Kendall and Kylie Jenner, on the red carpet outside the 2014 American Music Awards, and got their reaction to the scintillating snapshots.
"When I first saw it, I texted [Kim] a picture of it, and I was like, 'Killing it! This is absolutely amazing,'" a supportive Kendall told Rocsi. "I loved it."
"If you have the balls to do it, and the body to do it, go ahead," she told Rocsi. "People gave Kim so much crap when she was pregnant, and made her feel, like, so horrible about herself. For her to feel this good, and just kind of say, 'Okay, this is me.' Go for it. I mean, if you could do it, do it."
