And now, she has some strong words for her former flame.
"Karma," Gunvalson told Mario Lopez in a new interview for Extra about what she would have to say if she and Ayers crossed paths again.
She continued, "I hate him, I hate him with everything in me, and I don't hate people, but I believed him, I trusted him, I defended him, took a bullet for him when people didn't like him."
Ayers’ cancer diagnosis — and whether it was real — became a major plot point on Season 10 of The Real Housewives of Orange County. Ayers went so far as to produce documents from City of Hope, a cancer treatment center, to prove he had the disease. Earlier this week, those documents were shown to be fabricated.
"I'm completely shocked. I've seen the bills, I went to City of Hope," a tearful Gunvalson said during her interview. She also described a time she picked Ayers up from City of Hope after he allegedly told her he had completed his first round of chemotherapy.
"He was there all morning, so how do you think anything other than he's getting chemo? You go to City of Hope because you have cancer, not because you have nothing else to do during the day," she said.
As for her own involvement, Gunvalson says she had no idea the diagnosis wasn’t real.
"As God as my witness, I would never want to make something up like this; it's actually quite sick. I'm embarrassed. I want to tell the girls I'm sorry," she told Lopez, adding, "I'm guilty of loving him and believing him. Who hasn't believed someone that you loved? And why would you lie about cancer when I've had three friends die of it in the last two years? I had my dearest friend just die of stomach cancer."
