Khloe Kardashian sparks concern with her thin frame

American TV personality and socialite Khloe Kardashian's fans think the reality star's body is shrinking in new photos.

The 37-year-old reality star's appearance has changed dramatically over the years, and her ***tt is no exception, sparking concern with her thin frame.

As the Kim Kardashian's sister continues on her fitness transformation, many fans believe that her backside is slowly disappearing.

Recent pictures of the Kardashians star have shown off a different rear end to the one that she flaunted several years ago.

When Khloe was in her early thirties, her behind gained plenty of attention, especially in the hip-hugging skirts and pants that she favours.

With her back looking somewhat disproportionately larger than the rest of her, some fans speculated that she may have gone through a procedure.

Despite the surgery rumours, Khloe began to share more about her fitness regime with her followers on social media after Revenge Body with Khloé Kardashian premiered in 2017.

However, Khloe's fans wondered whether her gains could all be attributed to hard work at the gym. Her curves left fans doubting that her body was completely natural.

On Twitter, one asked: “Did Khloe have her ***tt taken out?”

Another wrote: “I think they [Khloe and Kim Kardashian] both realized that the ***tt-to-thigh ratio was looking too cartoonish so they got reductions. Which in my opinion looks way better than what was going on before.” 

While, some praised Khloe’s new physique, with one writing: “I think her current physique suits her well! Much more proportional.”
