Sources close to the situation confirmed to UsMagazine.com the 22-year-old is feeling dizzy and nauseas.
According to reports, Kris Jenner is out of the country for Paris Fashion Week but her father Caitlyn Jenner is by her side at a Los Angeles hospital where the reality star is receiving "top notch treatment."
Just one day prior to the medical emergency, Kylie was updating her social media with news about her Kylie Cosmetics brand.
Yesterday, she also shared a more personal note, writing that her "bae" Sofia Richie came to take care of her.
Kylie released a statement apologizing to her followers for missing Paris Fashion Week for the launch of her new makeup collaboration with Olivier. “Unfortunately I’ really sick and unable to travel. I’m heartbroken to be missing this show," she wrote on Twitter Wednesday.
"Sofia really helped Kylie through the emotional roller coaster during the Jordyn Woods situation," a source previously told E!.
Jordyn, Kylie's ex-best friend, said sister Khloe's ex-boyfriend Tristan Thompson kissed her at a party, which led to the end of the duo's longtime friendship.
"She was really there for her and took her side through everything. The situation with Jordyn made them closer."
