TMZ reports her father Caitlyn Jenner - who was known as Bruce Jenner before undergoing gender reassignment - has been at the hospital checking up on her, and whilst sources say she's getting expert treatment, it's currently unclear what her prognosis is.
Meanwhile, the 'Keeping Up with the Kardashians' star recently said she loves being told she can't do something, only so she can go and prove her critics wrong.
She said: "I get pleasure in doing things that people say I can't do."
Kylie was recently named as the world's youngest self-made billionaire, and has insisted she's grateful for her platform and her background for giving her the opportunity.
The lip kit mogul said: "I can't say I've done it by myself. If they're just talking finances, technically, yes, I don't have any inherited money. But I have had a lot of help and a huge platform. I didn't expect anything. I did not foresee the future. But [the recognition] feels really good. That's a nice pat on the back ... It's the power of social media. I had such a strong reach before I was able to start anything.
