White House party crasher and 'Real Housewives in D.C.' star Michaele Salahi has revealed in a new book that she has multiple sclerosis.

Salahi was diagnosed with the nervous system disorder seven years ago. The reality star appeared on a FOX News morning show on Wednesday and explained why she kept the illness a secret for so long.

"This is the first time I've said it publicly ... It's something I kept personal," Salahi said. "I think a lot of people do with chronic illnesses or any type of disease, whether it's heart [disease] or whatever you deal with, you know, breast cancer, so for me, I kept it personal because I never wanted to be judged, never wanted to have pity, and I certainly wanted to hold on to my job."
