Season 13 of "Real Housewives of Orange County" is turning into a casting nightmare for Bravo. After Meghan King Edmonds abruptly quit so she could take care of her growing family, there is reportedly a lot of drama brewing between vicki gunvalson and Tamra Judge. Now it's looking like the two "RHOC" stars are trying to set their alliances for the next season and make sure they don't end up outnumbered. It's turning into a huge casting nightmare!

Vicki Gunvalson trashes Meghan

Even before she announced that she as leaving the show, Vicki Gunvalson was busy trashing Meghan King Edmonds.

Back In December, she told Us Weekly that she didn't know why Meghan was even on the show at all. She said that her former "RHOC" co-star didn't even live in Orange County and kept a residence in St. Louis instead.

In January, after Meghan King Edmonds announced her departure from the show, Vicki took aim again, saying that she wasn't upset about Meghan leaving the show. She added, "We were never really friends anyways. She was tough to film with.”

Apparently, that has caused some drama for Vicki because Shannon Beador and Tamra Judge both bonded with Meghan King Edmonds during her time on the show. When it comes to sticking up for Meghan, Tamra Judge can be expected to take up for her friend over Vicki.

Now, it seems that those left standing are working to make sure they don't end up being singled out when everyone else on Season 13 of "Real Housewives of Orange County" is surrounded by their friends.

More 'RHOC' drama on the heels of Season 13 filming

In addition to the departure of Meghan King Edmonds, it looks like Bravo listened to viewers and won't be bringing back Peggy Sulahian or Lydia McLoughlin for Season 13 either.

That leaves three holes to fill in the "RHOC" cast and that has left the returning crew scrambling to bring in their friends.

Radar Online reports that both Vicki Gunvalson and Tamra Judge are racing to fill the "Real Housewives of Orange County" openings with their own friends. They are not trying to let Bravo cast all new replacements for the three housewives who are reportedly leaving.

As with many other Bravo hits, there are rumors that "RHOC" might bring back some old favorites in an effort to spice up the show and avoid casting new people. It's possible that Heather Dubrow and Gretchen Rossi may return.

That can't make Vicki Gunvalson happy. After Heather Dubrow left "RHOC" the first time, she reacted similarly to how she's acting now with the departure of Meghan King Edmonds. She made it clear that she wasn't upset to see her co-star go That time it was because of Heather's friendship with Tamra and Shannon as well.

As far as Gretchen Rossi's return goes, that could be an issue for Shannon Beador and Tamra Judge, who both took turns slamming the reality star while she wasn't even on "Real Housewives of Orange County." Bringing her back might help balance the cast, ensuring that everyone has drama with someone and that everyone has a friend on board as well.
