There is no love lost between Real Housewives of Beverly Hills costars Kim Richards and Lisa Rinna. The two women didn’t exactly get along last season on the Bravo reality series and according to Kyle Richards, the tension between them has spilled over into season 6.

“They left off in such a bad place last year that it was difficult,” Kyle told OK Magazine. “I didn’t even want my sister’s name coming up because of how everything ended. I was like, ‘I don’t want to talk about Kim.'”

To refresh your memory, Lisa questioned Kim’s sobriety while Kim claimed she knew a secret about Lisa’s husband Harry Hamlin.

Though Kim is no longer a series regular, the drama between her and Lisa seems inevitable considering Kim resurfaces later this season. And  based on the trailer, the drama is about to hit the fan.

“Obviously she and Lisa Rinna are not friends and it was horrible what happened between the two of them,” Kyle said. “I didn’t even see their whole conversation. [But] what I saw later, I was like, ‘Oh god!'”¬†

“It was awkward,” she continued. “And when we were filming it was uncomfortable too.”

“There are lots of things we want to put to rest and never get to seem to be able to,” she said.

So is there hope for Lisa and Kim to patch things up in the future? “Probably not,” Kyle said. “They disagree. They don’t get along and they don’t see eye-to-eye.”

The Real Housewives of Beverly Hills airs Tuesdays at 9/8c on Bravo.
