Meghan Kind Edmonds refuses to waiver in her belief that Brooks Ayers lied about having cancer during Season 10 of Bravo's "The Real Housewives of Orange County." Brooks has spoken out multiple times since the season finale, denying allegations that his stage three non-Hodgkin's lymphoma diagnosis is a farce. Edmonds, 30, believes the evidence Brooks has provided time and time again only further prove he's being dishonest.

In an interview with E! Online Meghan will acknowledge that suggesting that someone is faking cancer is a major accusation, but says she firmly believes it's true. Previews for the interview, which will serve as a follow up to Brooks Ayers sit-down with the network, which aired on Tuesday, show Meghan discussing her reasons for doubting him. She says she pointed out the inconsistencies in Brooks' story during Season 10 because she could not deny her feelings on the matter. She says her desire to expose him grew stronger once the other "RHOC" cast members began agreeing with her. Meghan tells E! she's seen the proof Brooks has presented, which include medical documents and bills for treatment, and she still doesn't buy it.

"To accuse someone of faking cancer is a huge accusation that you should never take lightly, but I felt that way and that's why I said it and that's what started it," she says. "To see the other women now say, 'yeah, you're right. It doesn't add up. It doesn't make sense. This is a lie,' it feels good because I'm not crazy. I have seen evidence and the evidence points to a lie."

During his interview with E! Brooks vehemently denied allegations about his diagnosis made by ex-girlfriend Vicki Gunvalson and the rest of the "RHOC" cast. He addressed a specific story, told during the Season 10 reunion, claiming he had been physically and verbally abusive to Vicki, 53, telling the network it was untrue. He also said he never told her he was dying from the disease, saying "she sensationalizes things."

During the final installment of the "RHOC" reunion Vicki finally admitted to her co-stars that she felt she had been duped by Brooks. She claimed she no longer believed his story, but stood by his side during Season 10 because she did not have enough proof that he did or did not have cancer. She revealed that she had "fabricated" some stories about Brooks' health throughout the season, specifically one involving Heather Dubrow's husband Terry. Vicki claimed Brooks did not have anything over her during the show, but said she was scared of him because of his tendency to be abusive, most of which she claims was verbal.

Meghan's sit-down with E! airs Thursday, Nov. 12, at 7 p.m. EST and 11 p.m. EST.
