Kylie Jenner was hospitalized in Los Angeles this week after experiencing severe flu-like symptoms, including nausea and dizziness.
Although the Kardashian-Jenner family matriarch, Kris Jenner, is in Paris, Kylie's father, Caitlyn Jenner, has been at the hospital checking on her quite frequently.
"Kylie's getting top-notch treatment right now," TMZ reported.
The Blast said things got so bad at one point that Kylie's throat "closed up."
Likely not by coincidence, Kylie had been recently telling her Instagram followers to drink tea and rest.
Still, despite her illness and hospitalization, the reality TV star and makeup maven has been keeping her eye the ball, so to speak, and has been promoting her KYLIE X BALMAIN makeup collection, which is set to be released on Friday night after the Balmain show during Paris Fashion Week.
After news of her illness was reported, Kylie took to Twitter to indicate that she won't be attending the launch party for her new line in Paris.
"Unfortunately I'm really sick and unable to travel," she wrote. "I'm heartbroken to be missing this show, but I know that my amazing team, and my friends who are in town for the event, will help me be there in spirit."
