Khloe Kardashian has reacted to a fan who claimed she had the cosmetic treatment.

A admirer of the 37-year-old reality personality alleged that she has butt implants. It all started when a Kardashian fan account posted an Instagram video of one of Khloe’s workouts.

The video, which shows Khloe wearing a purple gym set while exercising to music, received overwhelmingly positive reactions, with the exception of one comment that said: “When she stretches, you can see her implants. Her buttocks has a second layer on top of her bum.”

Kim Kardashian’s sister, who has a zero tolerance attitude for haters, addressed the criticism and disputed that her butt was anything other than natural. “Lol, stupid goose,” she said. “It’s the leggings’ seam design. That’s hilarious! You just want to believe anything negative.”

She has talked up about the “very terrible” attention she’s received for her beauty over the years, as well as being constantly compared to her sisters, Kim and Kanye West.

Khloe Kardashian walked out with her daughter True Thompson on Friday, revealing her slimmed-down figure in a basic black hoodie and skintight black leggings.
