Backstabbing, Threats & MUCH More! Yolanda Hadid's Nastiest 'RHOBH' Feuds Revealed In 10 Clicks

Yolanda Hadid just made her biggest Real Housewives Of Beverly Hills announcement yet — she's leaving the show! But with all this bad blood brewing, who could blame her?  

After announcing she was suffering from Lyme disease, tensions ran high after her not-to-supportive costars claimed that what Yolanda was really suffering from was Munchausen syndrome (basically, accusing her of faking her illness to get attention).  

"You have some balls!" the former model blasted when confronting Lisa Rinna about the matter. "No one has any evidence that Yolanda is faking it," sources told Star at the time. "But that won't keep the other ladies from saying otherwise."  

To make matters worse, Lisa Vanderpump also dragged her kids — who are also claimed to suffer form Lyme disease — into the nasty mix! “I’ve never heard in all the years I’ve known them, ever them, or anybody else, mention Lyme disease,” Lisa stated, making her skepticism known. But mama-bear Yolanda wouldn't have it, and showed her kid's medical records as proof of their disease and later demanded a public apology from her costar.  

As if her split from estranged hubby David Foster wasn't enough, one RHOBH costar decided to slam her for it! Heather Dubrow made sure to share her sympathies with Yolanda with The Daily Dish, but Heather's hubby, Terry Dubrow, took a very different approach to the already bitter divorce.  

"I think people who have a history of being married and divorced, get married and divorced," he dissed on Bravo. “If you’ve been married and divorced, two, three times, is it surprising? We are zebras; we have stripes. I think people are people [who] have patterns. If you get married and divorced, that’s what you do.”  

Things between Yolanda and 47-year-old Kyle Richards also ran far from smoothly throughout her stay on the show. The 55-year-old was far from thrilled when the actress used Yolanda's personal turmoil to gain media attention during the show's promo tour. “Yolanda thinks Kyle is trying to use her divorce and Lyme disease for publicity. And that Kyle is trying to cash in on her stories,” sources told RadarOnline.com when news of the fight broke.  

“Yolanda was treated pretty poorly by Kyle during filming,” the insider added.  “So she thinks it is pretty bad that all Kyle does is talk about her now. Every show Kyle is on, Yolanda is all she can talk about.”  

But their epic feud didn't end there. Kyle also hinted that Yolanda might be suffering form Munchausen's, the mom-of-three retaliated by claiming Kyle was bipolar and even got called out for it by Erika Girardi. “Lisa Rinna says you said she was bipolar,” she snitched. But Yolanda quickly denied the claims. “I could potentially call her bipolar but I would never do that because it’s not my place to do so," she stated.  

The bipolar-themed backstab only fueled the fire further, and caused for a heated showdown which ended in Yolanda warning her that she had a lot of other dirt on the star. "I hold a lot in the vault honey,” she blasted.
