Khloe Kardashian isn't the type to cancel a commitment.
But per doctor's orders Wednesday, the 31-year-old Strong Looks Better Naked author was forced to reschedule a book signing.
"Dolls! So sorry I needed 2 re schedule my book signing," she tweeted. "I'm sick &dr's orders are that I need to lay low until we narrow down what's wrong."
"I'll be going for more testing today," she continued. "I'm very sorry again. Stress can run our bodies down so please everyone take care of yourselves."
"Khloe has experienced fever, fatigue, and swollen glands. She has an infection but hasn't been diagnosed yet," a source tells E! News, while another insider explains that the celeb "has an minor infection and is being treated by her doctors. She is run down as she has been burning the candle at both ends. She will be fine but needs some rest."
Khloe's fans, for the most part, were overwhelmingly understanding of her needing to prioritize her health and well-being, and she took to Twitter to thank them for their support.
It's easy to see, as well, that she's been under a significant amount of stress since Lamar Odom was found unconscious following a drug overdose in a Las Vegas brothel on Oct. 13.
Fortunately, the former NBA player is no longer in a coma and is making improvements. He still has a long road of recovery ahead, though, and Khloe is committed to supporting him every step of the way.
She called off their divorce in order to help in making legal and medical decisions, but that doesn't mean she and Lamar are reconciling romantically. Khloe is still very much with boyfriend James Harden, which puts her in "a very unique situation," she explained on The Ellen DeGeneres Show.
Balancing a complicated personal life and a packed professional one can wear anyone down, and Khloe's no exception. We're glad, though, she's listening to her doctor and figuring out what's wrong.
