Like other cities in Bravo's reality franchise, The Real Housewives of Orange County features cast members who love each other but don't always act like it. From trips that turn into complete disasters and innocent parties that become full of yelling and tension, every moment on RHOC has the potential to become super dramatic.

Many fights have taken place between two co-stars, and sometimes there are larger arguments where the entire cast seems to be at odds with one another, or there is a rumor that persists throughout an entire season. The cast of RHOC hasn't always treated each other well.

The Cast Wasn't Thrilled About Braunwyn's Vow Renewal

Since Shannon Beador and Vicki Gunvalson each got divorced after their vow renewals, they weren't that happy to attend Braunwyn Windham-Burke's ceremony in the season 15 episode "Renewals and Regrets."

But the cast members could have put aside their personal beliefs and been there for Braunwyn, as this moment and milestone meant a lot to her. Instead, the cast seemed to have a negative attitude about the entire event.

The Rumor About Kelly In Season 13

Vicki and Tamra both mentioned that someone told them that Kelly Dodd was involved in a "train." This was a huge secret that the RHOC cast knew and when it finally got out into the open, it was extra dramatic.

No matter how the cast feels about Kelly and no matter what she has done to them, no one deserves to be the subject of a rumor, and no one wants their friends to talk about them behind their back.

Braunwyn Did Research On Elizabeth In Season 15

Braunwyn wanted to know more about season 15 newcomer Elizabeth Lyn Vargas and said that Elizabeth didn't have as much money as she claimed to. Of course, Elizabeth was hurt when she heard about this, and their co-stars didn't think that it was the right thing to do, either.

If someone does research on their co-star, it's always going to look like they don't trust them, and this is only ever going to be a recipe for disaster. It's also true that Elizabeth's finances aren't anyone's business but her own.

Kelly Hit Gina And Shannon On The Head

Of the best RHOC trips, the season 13 Arizona vacation wasn't the calming, meditative experience that it was advertised as.

Kelly grabbed a mallet and hit Gina Kirschenheiter and Shannon on the head. The cast then became divided as everyone was against Kelly here, wondering why she would do this.

The Gossip About David Being Unfaithful To Shannon

Shannon & David Beador renew vows on RHOC

Shannon and David's divorce was an incredibly tough period of time, and it seemed like rumors were flying around about their marriage when people first found out about the affair.

Shannon felt that Heather Dubrow was talking about it, and Shannon discovered that Vicki was discussing the subject as well, which was really painful. This was a moment when Shannon needed love and support.

Lauri's Claim About Vicki's Sex Life

The season 8 Whistler vacation wasn't just fun in the snow. Lauri Peterson talked about Vicki's sex life, which felt inappropriate and was one of the worst things that a cast member has said about someone on RHOC.

Vicki yelled "I have never been with multiple partners in my life!" saying that Lauri's comments were a lie. No matter what's true, why was Lauri talking about it?

Shannon Didn't Talk To Anyone In Jamaica

The decision to go to her hotel room and not talk to anyone on the Jamaica trip was one of the worst things that Shannon did on RHOC.

Season 13 wasn't a great time for Shannon as she dealt with her divorce, and while the cast wanted to talk to her and help her feel better, she felt that it was better not to speak to anyone for a while. Shannon's choice made her co-stars even more upset and concerned.

Gretchen's Partner Slade Called Vicki "Miss Piggy"

Gretchen Rossi's partner Slade Smiley wasn't very popular in season 7 as he did a stand-up routine and said that Vicki looked like "Miss Piggy."

This was a horrible moment and it was even worse that Gretchen didn't seem to feel badly about it. Vicki was looking for an apology and some recognition that this was embarrassing and insulting. Gretchen was upset that people were discussing it a party and said that she and Slade argued about his comments. It felt like Gretchen and Slade were on one side and Vicki was on the other, and it was easy to see why Vicki felt betrayed.

Tamra Left A Dinner In Bali Early

There are countless memorable Vicki and Tamra RHOC scenes, and there are some tough parts of RHOC where it felt like they would never be pals.

After Vicki said that Tamra had a "dark side," Tamra was distraught and yelled "You will never see my face again!" before leaving the dinner. Tamra felt that everyone was mad at her, as they called her a bad friend and Lizzie Rovsek called her "crap." It definitely wasn't nice of the cast to insult Tamra and make her feel bad.

Shannon Gossiped About Heather And Nicole

In the season 16 premiere of RHOC, fans met new cast member Nicole James and learned that she and Shannon used to know each other as their kids went to school together.

Right away, it became clear that there was a big secret lurking underneath. Shannon said that Nicole had allegedly sued Heather's husband Terry, which made the prospect of having a good time at Heather's big party seem unlikely. This made everyone feel uncomfortable as no one was sure about the truth.
