Vicki Gunvalson is done trying to kill all cancer -- or at least with the organization, Kill All Cancer.

The Real Housewives of Orange County
star helped launch the charity, which supposedly benefited the City of Hope National Medical Center, over the summer. But after a series of reports came out saying the charity was not registered as a non-profit and could be a scam, it’s been shut down.

“I just shut it down because there was a lot of naysayers out there,” Gunvalson told ET at the Mohegan Sun Casino’s 20th anniversary celebration in Connecticut on Saturday. “I'm not going to do something that's going to be criticized when I did it from a good place. And it wasn't my charity. I was just a spokesperson for it. So it wasn't mine.”

fans have watched as Gunvalson signed on to help with the charity, even filming a commercial for it on a recent episode.

Back in June, the 54-year-old gushed to ET about her work with Kill All Cancer. She got involved after her ex-boyfriend, Brooks Ayers, was accused of faking his cancer diagnosis. Ayers has denied faking his illness, but did admit to producing fake medical documents.

“Just to clear the air, I was never in on a scam,” Gunvalson told ET. “I have people and relatives that have died of cancer, and it’s way too serious for me. I've actually started a charity called Kill All Cancer … I'm giving back to research and to people that are suffering with cancer or suffer with cancer. We have wristbands, and it’s a transparent charity, and I'm gonna turn this all around and make good for it. Fifty percent of us are gonna be diagnosed with cancer. It’s not funny.”
