Tamra Judge and Vicki Gunvalson are currently at odds and at the center of their dispute is a charity.

Following their Real Housewives of Orange County season 10 feud, which was due to Brooks Ayers allegedly faking his cancer diagnosis, Judge has taken aim at Gunvalson for her charity, Kill All Cancer, which she believes is nothing more than a money scam.

"Am I the only one that doesn’t know what to think about Vicki starting an insurance program for cancer patients?” Judge explained in her latest Bravo blog, via a report by The Inquisitr. “The way it was explained was more about making money and convincing people she had nothing to do with Brook’s cancer scam. Michael sure called her out on some of her lies. Yikes.”

During season 10, Gunvalson was involved in a romance with Ayers, who claimed to be suffering from stage 3 Non-Hodgkin's Lymphoma. However, his illness was questioned by several members of the cast and ultimately, he was caught lying about his health. A short time later, Gunvalson's split from Ayers was confirmed. Still, several of her co-stars believed she was involved in the cancer hoax and have yet to forgive her for her alleged lies.
