Her sisters are known for taking perfect selfies, but it appears Khloe Kardashian may be getting some assistance. The Kocktails With Khloe star was forced to come clean about retouching an Instagram photo after fans found evidence of enhancements.

The altered image features Kardashian, 31, showing off her toned abs while pulling down her workout leggings. However, her Instagram followers noticed a curve in the door frame next to her thigh leading to suggestions the photo had been enhanced. The barrage of criticism prompted the E! TV star to remove the image before later replacing it with what she reveals is the original untouched photo.

In the new caption, the Keeping Up With The Kardashians star slammed her critics writing: "If only hatin burned calories how dope yall would be. Too bad it doesn't. Here's the OG shot. The petty movement ain't cute. Oh and I almost forgot.... Namaste." Perhaps as an indirect message to the "haters", Kardashian's longtime stylist Joyce Bonelli posted a photo of the reality star with her abs on show in a crop top.

During an episode of Chelsea Handler's Netflix series Chelsea Does, Kardashian admitted to using the app FaceTune, which allows the user to eliminate imperfections and change the lighting. She said: "Facetune is the best thing to bring to the table. It's life-changing. It's the only way to live," before adding of social media culture: "It's not real, you are presenting to the world what you want them to believe you are. It's amazing. I think our society nowadays is so caught up on getting validation from the social world that no one really knows, so they post these things."

In July 2015, Kardashian was forced to hit out at claims that her revealing photo shoot for Complex magazine had been drastically altered, giving credit to strict gym sessions for her toned body. Sharing a side-by-side of the untouched and altered images, the TV personality wrote: "This one is for all the troll haters out there that cannot seem to give me an ounce of credit for my daily workouts!

"The image on the left is an unretouched photo from the actual camera on the day of the shoot. The image on the right is the retouched photo. Yes skin is smooth and shadows are removed but I still think I look good on the left image. Flaws and all."
