Sources close to the ‘Keeping Up with the Kardashians’ star told the publication: “Kendall was prepping for appearances during Oscars weekend, and suffered a bad reaction to a vitamin drip.” The Blast reports that the brunette beauty checked herself into Cedars Sinai hospital in Beverly Hills where she was treated for the reaction to the vitamin infusion, and was released a short time later.

No more details are known about Kendall’s reported hospital visit as of the time of writing, but it seems she is fighting fit once again as she was spotted looking fabulous at the Vanity Fair bash at the Wallis Annenberg Center for the Performing Arts in Beverly Hills on Sunday night.

It comes after Kendall recently dubbed herself as a “hypochondriac” – which is a person who overanalyses any symptoms they may have and believes they are suffering from serious illness – and admitted she needed to start being a “big girl”.

“Since I was a kid, I’ve always been a hypochondriac. I’ve always been the worst hypochondriac. But now I have to try and be a big girl,” she said.
