How Dare You! Yolanda Foster Confronts 'RHOBH' Co-stars For Questioning Her Lyme Disease Diagnosis

Yolanda Foster is on the mend and fighting back! RadarOnline.com has learned that the reality star is ready to confront her Real Housewives of Beverly Hills co-stars after they questioned her Lyme disease diagnosis.

David Foster's wife is "getting ready to film with ALL of the ladies of RHOBH in the next two weeks," an insider revealed. "Since having her breast implants removed, Yolanda has had a huge improvement in her overall health. But she still suffers from Lyme disease."

"She was beyond hurt after finding out that some of the ladies were asking a lot of questions and even suggesting that she didn't even have it," the source said. "She was particularly upset with Kyle Richards and Lisa Rinna for not sticking up for her when she wasn't around, and now she is ready to spill all of their dirty secrets!

In addition, "Yolanda plans on having heated words with Taylor Armstrong because she wasn't even around at the height of her illness," the source said.

Up until now, Foster had been very reluctant to return full time to the show. "She feels that producers have pitted the ladies against her regarding the Lyme disease diagnosis," an insider previously told Radar.

But with her health improving, "Yolanda is now firing on all cylinders again," said the source. "You don't want to mess with her! She will use RHOBH to continue to raise awareness for Lyme disease, and finding a cure. She doesn't want anyone else to go through the hell she has."
