'RHOBH' Kyle Richards Reacts to Lisa Rinna & Kim Richards Glass Throwing Incident — Whose Side Does She Take?

Another person is weighing in on the Lisa Rinna and Kim Richards feud, and it is the person that Kim was hoping would come to her defense the whole time, her sister Kyle Richards. While Kyle told Kim during her and Lisa's epic blowout in Amsterdam that her behavior was "indefensible," it seems that today she has her sister's back.

During last night's episode Kim and Lisa got into a verbal argument regarding Richards' sobriety, which quickly turned into a physical altercation when Rinna threw her wine at Kim and then broke the glass on the table.

According to Radar Online, Kyle spoke out about the fight on her Twitter page, saying that while Kim's behavior and the way she was speaking to Lisa was definitely unacceptable, that is was also not appropriate for Rinna to throw the glass.

A Twitter user wrote to Kyle about the incident, saying, "Kim was outta line but why it is okay 4 Lisa 2 go 4 Kim's neck & throw a glass?"

Kyle tweeted back at the user writing, "It's not ok!"

While Kyle revealed that her and her sister haven't spoken in four months, it seemed that she kept coming to her sister's defense on Twitter.

The starlet also called into Watch What Happens Live to talk about the events that occurred with Andy Cohen. Kyle seems to take a middle of the road stance, saying that both women's behavior was inappropriate.

"I just couldn't support that behavior, and what she was saying to Lisa," Richards told Andy. "It was wrong of Lisa to throw the glass absolutely, and you know the whole thing was such a nightmare."

When Andy asked why no one really was talking about the glass throwing, Kyle said it was because all the women were shocked by her actions.

"That's never okay, I mean all of us were shocked we had never seen anybody do something like that except in the movies, and it was just unbelievable," Richards explained. "All the women were just traumatized after."
