'Real Housewives Of Orange County' Season 10, Episode 12: Vicki Gunvalson Threatens To Take Down Meghan King Edmonds During Heather Dubrow's Luncheon [RECAP]

Things are heating up in the feud between Meghan King Edmonds and Vicki Gunvalson on “The Real Housewives of Orange County.” The pair first butted heads during a group vacation in Tahiti, but tensions truly came to a boil after Meghan, 30, shared with Shannon Beador -- perhaps Vicki’s, 53, closest friend in the group -- that Tamra Barney’s psychic insinuated Brooks Ayers did not really have cancer. Vicki made a point to avoid Meghan as much as possible, but a luncheon at Heather Dubrow’s partially built new house in episode 12 forced the pair to confront one another.

Heather, 46, gathered the group at her and husband Terry Dubrow’s massive home, which is still under construction, for lunch and a tour. Not long after arriving at the shell of a mansion Vicki and Meghan came face-to-face. The pair remained cordial despite their differences, but it wasn’t long before the afternoon took a turn for the worst. While sitting down for the catered multi-course meal Heather helped put together, Meghan questioned Vicki for having been upset about her comments in the previous episode. Vicki exploded into a rage, bashing Meghan for doubting Brooks’ diagnosis. She suggested that it was unchristian of Meghan to insinuate that and slammed her for being immature at which time the “RHOC” rookie called Vicki “old” and “bitter.”

In episode 11 Meghan and Heather sat down with Tamra Barney’s psychic for lunch and a reading. During their get-together the trio brought up Vicki and Brooks in the hopes that the psychic would be able to pick up on them despite their absence. It was then that the ladies were told that, although he was able to read them, he did not see any cancer. Meghan, Heather and Tamra, 46, were in agreement that the best way to proceed was not to bring up the reading again. Unfortunately Meghan was only able to hold the secret until later that evening when the whole “RHOC” cast gathered at Cut Fitness for a workout class and a celebration of Brooks’ birthday. After learning that Brooks had decided to forego chemotherapy in favor of a less traditional method of healing, Meghan shared with Shannon, 51, what the psychic had told her. In an attempt to be a good friend, Shannon brought the information to Vicki later that evening during Brooks’ birthday dinner. Unfortunately it resulted in a fight.

As ugly as tonight’s episode was for Vicki and Meghan, it looks like next week may be even worse. The “RHOC” OG and young newcomer will confront one another yet again, and this time it looks like Meghan’s husband, Jim Edmonds, is getting in on the feud.
