Is Yolanda Foster the new Brooks Ayers?

Kim Richards & Yolanda Foster: Victims Of Bullying On 'RHOBH' Season Six?

While Foster has been open with her Lyme disease for years, rumors began swirling during filming on The Real Housewives of Beverly Hills season six, alleging she could have something to hide. However, according to a new report, Foster isn't faking her diagnosis—and is willing to provide proof of her illness.

“She seems to be the center of all of the drama,” an insider told Radar Online on December 1. “The ladies have continued to question her Lyme disease diagnosis, all behind her back. Knowing the cattiness of the ladies, Yolanda isn’t surprised about the whispers, but just wishes it would have been expressed to her directly.”

'RHOBH' Star Eileen Davidson Comments On Yolanda Foster's Lyme Disease

Foster was diagnosed with Lyme disease in 2012, and since then, she has chronicled her battle with the illness on social media, and spoken of her hardships on the show.

“Yolanda watched how Bravo handled Brooks’ cancer scandal,” the source continued. “She won’t tolerate this playing out as gossip fodder or allow the show to minimize the seriousness of what she has been through. There are binders of medical reports, lab test results that Yolanda has, and will go public with. She has absolutely nothing to hide.”
