Kelly Dodd Rails on Vicki Gunvalson After Threatening to Quit 'RHOC' Over Cocaine Accusations

Kelly Dodd came out swinging this week against Vicki Gunvalson, after the latter accused her of using cocaine during the upcoming "Real Housewives of Orange County" reunion.

"If they don't do something to Vicki how could I go back … I'm not going to sell my soul for this ratchet liar!” Kelly reportedly said to a fan Tuesday on Instagram. "They [are] running that show to the ground and hurting people's reputation and my brand."

When someone suggested both Vicki and Tamra Judge leave the show, she added, "They can have her I'm out! I don't need this shit!"

A Bravo source tells TooFab no casting decisions for the next season have yet been made.

Dodd was just getting started, however, and continued to rail on Gunvalson in an interview with PEOPLE on Wednesday night. "It's been really horrible," she told the publication. "I don't do drugs. I don't do cocaine. I've seen it ruin families, I've seen it affect people close to me. I'm constantly telling my daughter Jolie to avoid drugs I can't stress it enough to her."

"But by Vicki saying that there are all these people out there believing it," she continued, "Now it's out there in the universe. You don't think people are going to be like, 'Maybe she does do it?' This is my life. This is my name. It's like character assassination. It's really hurt me."

She added that it's been especially hard on her daughter, whose friends' mothers all watch the show. "My daughter's been crying, thinking that her friend's parents aren't going to let her see them because they'll think that I do drugs," added Dodd.

Though the two apparently left the reunion "in a good place," the reaction to the cocaine accusation since the reunion trailer dropped has made Dodd rethink things. "She is so far off base, how can I have a relationship with her?"

The "RHOC" reunion kicks off Sunday night on Bravo.
