On the next episode of Bravo's "Real Housewives of Orange County," Vicki Gunvalson isn't ready to let newbie Meghan King Edwards off the hook after making a comment about her boyfriend just yet. During a lunch party, Edwards attempts to squash the tension between her and the OG housewife, but Gunvalson responds with a threat that even Edwards didn't see coming, People reported.

In a previous episode, Gunvalson's boyfriend Brook Ayers announced that he was not cancer-free and was preparing to undergo an alternative treatment. But during a session with Tamra Judge's psychic, the psychic said Ayers might be faking his diagnosis.

The topic was brought up again in Judge's booty workout class and Edwards said she didn't believe Ayers had cancer. Fellow housewife Shannon Beador told Gunvalson about Edwards' comment during a birthday dinner and Edwards attempts to clear the air at lunch.

"Vicki," Edwards says. "Shannon was telling me that the other night you were upset because Shannon said something to you at dinner about me saying something negative about Brooks."

"Absolutely," Gunvalson replies.

"And then Tamra told you that the psychics, I said that..." Edwards tries to continue, but Gunvalson cuts her off.

"Absolutely, and I say this, thank you Jesus, thank you Jesus he's cured," Gunvalson says. She threatens Edwards, waving her finger at her. "Don't you ever question if he has cancer again, I'll take you down."

Watch the ladies' catfight below and don't miss tonight's episode of "Real Housewives of Orange County," airing at 9 p.m. EDT on Bravo.
