And she's trying her best to keep it all a secret.

Kim Kardashian has been diagnosed with a serious medical illness, and she has been trying to hide it from her friends and fans, Radar reports. The outlet claims that whatever it is, it's worse than her Paris robbery and Kanye's mental breakdown.

"About three weeks ago, Kim received bad medical news. Kanye has been stressed about the diagnosis and that was part of what is to blame for his demise," the source dished. "Kim’s friends have heard she was diagnosed with a major illness, and is not going to be OK. Her friends are worried and trying to find out what’s going on,” another source added.

"That’s part of why Kanye flipped out. The family isn’t telling anyone yet. After the robbery, Kim went to see all sorts of specialists. She got a diagnosis and has started taking medication. She’s following her doctor’s orders and is working through it, but a lot of people around her are scared," the insider revealed.

If it was something as simple as PTSD or another mental illness we don't think the source would say she is "not going to be OK," so what could it be? Your guess is as good as ours, but we hope Kimmy K's life isn't in danger.
