The reality star showed off her bum, while fans continue to speculate that she has had her butt fillers removed.
In a series of new photos shared on Instagram, the 41-year-old walked across a white sandy beach and snuggled up to a palm tree.
Kim was wearing a silver and black top, and a bikini that covered much of her rear.
In the first photo, the SKIMS founder looked over her shoulder at the camera, showing off her slender butt.
Rumors have already circulated that Kim had undergone a Brazilian butt lift to get her distinctive butt.
Other people have weighed in online with their thoughts, questioning whether Kim's seemingly shrunken rear end is a result of having fillers removed.
In August, fans wondered about her less-than-slim bum after the star shared a photo posing in tight leggings while holding Salmo, her youngest son with ex-husband Kanye West.
The difference didn't escape fans, with one asking, "Did you shrink your butt?"
Others wrote: "I swear your butt looks so different" and: "What happened to her booty?"
Meanwhile, one surgeon told OK! magazine, "Something was removed. Either she had butt implants removed or she had filler dissolved or liposuction to reduce the size of her butt."
Mark Ho-Asjoe explained, "The main difference with Kim's bottom is the emptiness at the top compared to her before photos."
