The reality star admitted she was ‘freaking out’ about the strange detail, as fans joked it was ‘a case for the FBI’.

Kim Kardashian has shared a haunting selfie on her Instagram after spotting a strange detail in what was supposed to be a routine picture.

The 42-year-old reality star, who is well known for her love of selfies, posted the photo so her 362 million Instagram followers could observe the detail.

The photo showed Kardashian in a pink dress she appeared to be altering, with her dark locks tied up in a messy top knot.

Neutrally posing for the camera, it was not until later that Kardashian noticed a figure in the reflection.

It appeared to show the reflection of someone gazing in from outside a window, despite the reality star ensuring that she was alone.
