'Real Housewives of OC' Vicki Gunvalson Fights With Brooks On Twitter After Cancer Lie Exposed

It's getting dirty in the OC! Real Housewives of Orange County star Vicki Gunvalson and ex-boyfriend Brooks Ayers are going at each other on Twitter and in the media after conflicting accounts about his cancer lie. The day after Vicki's sit-down with Andy Cohen on Watch What Happens Live, Brooks blasted his former love by contradicting her statements on the Bravo show.

"Vicki keeps saying she hates me and is not going to talk to me ever again and that I duped her," he told E! News. "She was texting me just last night! We were bantering back and forth about some of the things she had said on the special."

The Mississippi businessman then shockingly divulged that he "called her out on a lot of it and she basically said it was something she had to do to protect herself."

However, Vicki told E!, "It is not true at all. I did not reach out to him. He is lying."

So who is telling the truth?!?!

In an interview with The Real Mr. Housewife, Brooks said "the OG of the OC" used his cancer diagnosis to gain sympathy from her costars and public because they turned on her for dating him.

"She was not involved in my treatment," he told the reality gossip site. "She presented to the world that she was an involved caregiver but she was an absent caregiver. It makes me sad she makes up stories to make herself look better. Insecure people tear other people down, while secure people try to build others up. She's not the victim here and time will demonstrate that."

Vicki decided to respond to Brooks's accusations on Twitter which caused a nasty fight between the two through social media.

"You are the one who contacted me & yes I have responded . I am the one who was USED! Do you want to go there?" she wrote.

"You're the one who sent me your agenda for Florida plus got mad when I didn't respond this weekend," he fired back. "Another lie! I got mad that you lied about your false medical records!" she tweeted in response.
