Camille has fought with several cast members from Kyle to Dorit, and when fans think about Camille, they can't help but remember the scene when Kyle said, "You're such a f**king liar, Camille."

Camille's most iconic scene is when she talked about the end of her marriage. She said that she had gone to New York to see her husband Kelsey Grammer in his Broadway play and realized that he was cheating on her. When she went to their apartment, the doorman said, "You're not Mrs. Grammer" and said that the other woman was calling herself that. It was a rough way to find this out, and Camille was distraught, saying, "Does she not know that she's destroying a family? She's destroying my children. They're going to be just devastated without their dad."

Taylor was upset because Camille had been talking about their relationship, and Taylor and Camille began arguing. This fight took place at a party, as the title of the episode suggests, and even before Camille arrived, Taylor said she was really upset and overwhelmed.

The season 10 premiere of RHOBH brought up many questions and things only got more dramatic as the episodes went on. Brandi appeared on the show from seasons 2 to 5 and 9 to 10, and she also appeared in season 6. Many would consider her an OG housewife as she had a big influence.

In her most iconic scene, Brandi brought up a rumor that became the storyline of season 10: she says that she and Denise Richards slept together. Brandi met up with Kyle, Kim, and Teddi and got super emotional, talking about how she was cheated on before and was very upset about what happened, as she felt that she was the cheater. Brandi explained that she visited Denise and they slept together, and she said that Denise told her not to tell her husband Aaron.

Dorit and Kyle went to Lisa's house and Lisa read them text messages from Teddi, and this became Lisa's most well-known scene. Teddi wrote, "Have the dog there and I can say that it looks like Dorit's dog." Kyle said, "There's no doubt that her hands aren't clean in this" but it wasn't only Teddi who was involved. This was awkward as Teddi had always maintained that she was telling the truth 100 percent.

Kyle Richards: When She Called Kim An Alcoholic And They Fought In The Limo

In the season 1 finale "Unforgivable," Kyle and Kim rode in a limo together, and Kyle called her sister an alcoholic. She also said she was a liar and "sick." This was a very tense and tough moment to watch, and while Kyle's behavior and words seemed super harsh, she was ultimately concerned about her sister's well-being and her emotions seemed to get the best of her.

Fans remember this scene as the most crucial one in Kim and Kyle's relationship and it was definitely a turning point for them. Once Kyle shared how she felt, things changed forever. In more recent seasons, Kim has returned and fans have seen a much healthier and happier version of this former RHOBH cast member.
