Jenner, 22, said on Twitter that she was sick and unable to travel to Paris to launch the collection as planned on Friday with Balmain Creative Director Olivier Rousteing.

The “Keeping Up with the Kardashians” star did not give details of her illness but celebrity website TMZ.com said she was admitted to a Los Angeles area hospital earlier this week with what an unidentified source described as severe flu-like symptoms, including nausea and dizziness.

Jenner’s representatives did not return a request for comment on Wednesday.

“Unfortunately I’m really sick and unable to travel. I’m heartbroken to be missing this show ... Creating this collection with Olivier has been a dream,” she said on Twitter.

Jenner, whose lip gloss kits and other cosmetics have made her a billionaire, was due to launch the Kylie X Balmain line of eyeshadows, lip liner and lip gloss on Friday at the Paris fashion show. The line is to be worn by Balmain models walking the runway for the Spring Summer 2020 collection.

Jenner was also absent from the Emmy awards show in Los Angeles on Sunday where she was due to present an award with Kim Kardashian and her model sister Kendall.
