'Real Housewives of Beverly Hills' star Kyle Richards says costar stormed out of her house after 'big fight' in 'tumultuous' season 12

• Kyle Richards said a "Real Housewives" costar stormed out of her house after an argument.
• The original "RHOBH" star teased that season 12 is going to get even more "tumultuous."

"Real Housewives of Beverly Hills" star Kyle Richards has teased that season 12 of the hit Bravo reality show is about to get even more "tumultuous" as viewers will see her have a "big fight" with one of her fellow housewives.

"There's just a lot going on, a lot of drama, a lot of arguing, a lot of jaw-dropping moments," Richards teased at a special screening event hosted by Hayu, which airs "RHOBH" internationally, in London earlier this week.

The original "Beverly Hills" housewife said that in upcoming episodes, one of her costars will be seen storming out of her house after an argument.

"I clashed with people that I care about. There was some stuff going on with some of the girls — one of them, we had a big fight and she left my house," Richards said.

"I think the viewers will like it a lot. Whenever I say it's a great season, it's not great for us — it's great for the viewer. It feels so weird to say that: 'It's so great! We're all so tormented! You're gonna love it!'"

Richards, whose husband Mauricio Umansky also made a surprise appearance at the London event Monday, didn't reveal which of her costars she clashed with, but things have been pretty tense in "RHOBH" land this week.

On Tuesday night, Richards responded to criticism after two preview clips from this week's episode of "RHOBH" had fans on social media in an uproar.

In one clip, Richards appeared to minimize costar Sutton Stracke opening up about past miscarriages, telling Stracke: "I love you, but this feels like bullshit."

In a second clip, Richards, Umansky, costar Dorit Kemsley, and Kemsley's husband, PK, appear to laugh off Erika Girardi cursing at Garcelle Beauvais' 14-year-old son, Jax.

Richards explained her version of events on her Instagram Stories, telling fans that she had "obviously had a few drinks" when talking to Stracke "and didn't express myself clearly."

"I was disappointed in the way I handled myself altogether," Richards continued. "When I woke up the next morning I thought about what happened and I realized that maybe Sutton was sharing her story with Diana to connect with her in some way. I immediately called Sutton and apologized to her. I consider Sutton a close friend and care about her a lot. Sutton accepted my apology and we moved on."

Responding to the second clip, Richards said she hadn't witnessed Girardi telling Beauvais' son to "get the fuck out" of his mom's birthday party, and clarified comments she made about Girardi's behavior being "funny."

"I meant Erika being drunk was funny, but what she said to Jax was not," Richards wrote. "I hope you know me well enough by now to know I certainly do not condone speaking to children like that."

Richards added that she felt "absolutely terrible" watching the clips that have been circulating online.

"The Real Housewives of Beverly Hills" airs Wednesdays on Bravo in the US, and is available to stream on Hayu in the UK and elsewhere the next day.
