American reality star and businesswoman Kim Kardashian, who is known for her glamorous pictures, was horrified to see a mysterious shadow of a woman in the background of her latest selfie.

In the mirror selfie shared on Instagram on Sunday, the SKIMS founder looks stunning in a pink tank dress without makeup, and has her hair tied in a top knot.

But the 42-year-old revealed her true fear in the caption of the photo, writing: “I took this picture last week when I was alone and now when I look at my phone I see a woman in the window and I panic “

The mother of four’s scare forced her fans to flock to the comments section to offer their theories on what the phantom was.

Fan responded, writing, “Can you imagine you’re a ghost and you’ll know you’re on Kim Kardashian’s Instagram.”

Another chimed in: “If I were a ghost I would definitely be in Kim’s house.”

The third wrote: “It’s time to call the priest.”

While some of Kim’s followers believed the figure resembled Kim’s mother Kris Jenner, some speculated it was pregnant sister Kourtney Kardashian.

“That’s Kourtney. She wants revenge for her marriage,” wrote one.

Another quipped, “It’s Kourtney trying to outdo your next move.”

The fan joked: “American Horror Story: The Kardashians.”

It looks like Kim Kardashian’s followers were horrified too, but they left some hilarious words in the comments section.
