This summer, "Real Housewives of Orange County" star Vicki Gunvalson broke up with her boyfriend of four years, Brooks Ayers. The cause of the breakup is unclear, but many think that the star will give some answers on the show's reunion special. The 10th season of the reality series is on its way to a close, and fans cannot wait for the reunion show to see if there will be some revelations about her breakup, and moreover, Brooks' health condition.

Throughout season 10, some of the ladies of the OC have speculated a lot about Brooks' health, claiming that he is faking his cancer diagnosis. While the season was being filmed, Vicki and Brooks were still together and she would often come to his defense if any of the ladies talked about him faking his cancer. Now, a new report claims that after taping the reunion show earlier this week, the 53-year-old's outlook on her ex "has completely changed."

According to a source from RealMrHousewife, Vicki "went into the reunion believing Brooks 100 percent, but after seeing and hearing things from the women, Vicki doesn't believe Brooks at all."

"In fact, she thinks his cancer was faked and she no longer believes anything she told her," the insider added.

It is unknown what made Vicki change her mind about Brooks, but Starcasm reports that the Bravo star recently shared some details about the reunion and Vicki said that she was disappointed in some of the ladies during taping.

"They wanted me to admit something that wasn't the truth and I wasn't going to. You'll find out," she said.

The Housewives started thinking that Brooks may be faking his cancer after he told them that he has stopped his treatments and has turned to alternative medicine and treatments. On the show, Meghan Edmonds said that she got in touch with a former girlfriend of his, who allegedly said that Brooks also faked his cancer in the past.

"The Real Housewives of Orange County" airs on Mondays at 9/8c on Bravo.
