Vicki Gunvalson Thinks Brooks Took Eye Drops To Fake Cancer

As Brooks Ayers' cancer lies continue to unravel, ex Vicki Gunvalson sets the record straight on her side of the story.

In a sneak-peek of a special one-on-one interview on Watch What Happens Live, the Real Housewives of Orange County star sits down with Andy Cohen to discuss new revelations on the drama.

"Brooks had to fabricate this lie all the way prior to filming, because he got diagnosed in September/October of 2014," Vicki told Andy of her ex-boyfriend's potential cancer con. "We are now in November of 2015, so this lie had to be fabricated and thought out long before filming."

As RadarOnline.com previously reported, Brooks still maintains he has cancer, though he admitted to fabricating hospital documents in an exclusive interview with E! News.

"You said that when Brooks does chemo he gets a fever he starts vomiting…for about five days," Andy commented, asking, "but knowing what you know now, what do you think caused him to become so sick those days?"

"I actually contacted a couple of people, and they said you can actually take eye drops and it can make you violently ill," Vicki answered, her eyebrows raised. "I don't know if he did that, that's pretty sick, but I witnessed him with fevers and white sweats and chills. I mean, he lost 42 pounds in three months."

"The extent of what I did for this man to try to cure him, I can't even tell you," she continued, shaking her head in disappointment. "Time and money, and time and money, I spent on him."

The reality star previously lashed out at claims that she was complicit in Ayers' cancer lie, telling RadarOnline.com exclusively that she tried to avoid talking about his diagnosis on the show altogether.

The Watch What Happens Live One-on-One with Vicki Gunvalson airs Monday, November 23 at 8:30 pm ET on Bravo.
